Over the past day (not yet recorded here) I've learned a fascinating amount of detail about vampony culture. To centralize all of the important information, I'm writing a comprehensive glossary here before I go into details about the events.

I'll share some of the conversations that led to the following information in the next few entries.

aconitum: flowering plants of the wolfsbane family, most species of which are highly toxic. Close proximity to aconitum automatically blocks the wolf. Although vamponies are immune to the toxic effects of aconitum, for the safety of other animals they only cultivate species with low toxicity.

baubles: badging accessories vamponies wear that secretly project their rank (see materials for more) and owner. The latter is noted by a hidden mark visible only with vampony sight or a mana-based light source. The hidden mark glows slightly, which allows vamponies to distinguish true baubles from copycat jewelry at a distance of up to ten meters. Baubles can be used for show (collars, earrings, and saddles), or used to block the wolf (currently these include hobblers, hollows, horncaps, ounckses, shredders, and wingclips). Many baubles can be locked so that the user cannot remove them. Masters wear only earrings and (optionally) collars.

bitch: a term of endearment used by Masters and Ladies to refer to cunts who are currently under their control. See also sister-bitch.

block the wolf: to prevent letting out the wolf. There are three ways to block the wolf: close proximity to aconitum (only by Master permission), concentration alone (for Masters who can hold the wolf), and wearing baubles designed for this purpose (for Ladies and cunts). Note that not all of the wolf can be blocked: enhanced hearing, enhanced smell, fangs, and prehensile tongue are always available for a vampony to partially let out.

bloodhorn: a unicorn vampony, like Rarity or Shining Armor. When letting out the wolf, the horn of a bloodhorn curves upwards, turns smooth, and reddens toward the tip. (It doesn't become sharp unless the horn was already sharp.) Ounckses and horncaps will block the wolf entirely. King Sombra was the first bloodhorn: he ascended to power after learning of Princess Luna's discovery of the vampony mutation.

break: to destroy a pony's stain with a Breakstone.

Breakstone: one of many magical artifact stones originally from the Crystal Kingdom which have been repurposed to destroy the stain, thus breaking the pony.

control: for a Master or Lady to dominate a pony. The pony does not need to be owned, but permission from the pony's Master is required. Control without ownership usually happens when a cunt is away from their owner, when the owner allows it for recreational purposes, or when the pony is on the market. Multiple Masters (or multiple Ladies) may mutually control a cunt if they agree to, but this is typically done only in two settings: informal situations, and recreation. (By recreation, Cadance used 'giving a cunt a real workout' as an example. I don't want to know what that means.)

cornectomy: the amputation of a horn, which is commonly done to unicorn Ladies and lost ones. A cornectomy can be hidden within a realistic fake horn. I cannot possibly fathom why anypony would do this willingly, even if sex is involved. In theory, if I took my brother's dick up my ass, somehow all of this would magically make perfect sense. (That was sarcasm.)

cunt: a vampony who isn't a Master, except that Ladies may only be referred to as cunts by a vampony who controls them. 'Ladies and cunts' is, therefore, more inclusive. All lost ones are cunts, regardless as to who is addressing them.

cutie dark: also occasionally called a "dark mark", this is the name for the changed cutie mark that results when a vampony lets out the wolf. The only two I've seen so far in pony, since I didn't get a good look at Rainbow Dash's cutie dark: Fluttershy's (no, I won't use her nick) cutie dark is a trio of bats (instead of butterflies), and Pinkie Pie's is a trio of colorful horse sperm (instead of balloons).

darkhoof: an earth pony vampony, like Big Macintosh (who might actually have been the first). Darkhooves produce mudblood from their splits when they let the wolf out, and they gain incredible balance and dexterity (via the splits). Hobblers and hollows will block the wolf entirely.

emancipated: Ladies and cunts who wear special, non-disabling baubles which still block the wolf. This is done for vamponies whose abilities are too important to the Order, or ponies whose work would otherwise require frequently removing baubles (like a Wonderbolt performing). Vamponies are not permitted to be emancipated while on the market. Despite the name, emancipation has no effect on a vampony's rank. See materials for details on how to spot an emancipated vampony.

fixed: not yet broken.

fixed-up: this refers to ponies who haven't been broken, and it also implies that somepony is sexually confused. So, let's review: you're insane if you don't want to fuck your parents and get a lobotomy. (That was also sarcasm.)

fractal: a crystal pony vampony. When they let out the wolf, fractals gain the appearance of a wildly shifting, faceted interior. This produces an effect that mesmerizes any sapient creature who stares into it for more than a few seconds. Other vamponies are immune to the effect. Rarity isn't sure how to make a bauble that blocks the wolf for a fractal yet, but they've only converted a few from the Crystal Guard whom they (surreptitiously) had already reaped as Masters.

hobblers: a more severe form of hollow that is also extremely heavy. The weight makes kicking virtually impossible and walking becomes a workout, even for earth ponies (who are the only ponies who can even move in them). See hollows for additional information.

hold the wolf: to let the wolf out without losing control of one's mind. This technique is taught to Masters, and only Masters are permitted to use it. This also allows the Master to block the wolf at will.

hollows: a bauble which blocks the wolf in earth ponies by constricting the hoof. These are shoes with a vacuum layer that also inhibit an earth pony's manumancy. The emancipated version of this bauble is just a normal shoe that fits tightly around the hoof.

horagon: a dragon vampony, which Rarity knows about because Spike tasted the wolf once in her presence (dammit, Spike). When horagons let out the wolf, their tail thickens and becomes a prehensile phallus. Rarity is working on a thick tail ring bauble which should block the wolf for a horagon.

horncap: a bauble that is a cap with a metal base screwed tightly onto the nub of a cornectomy. It prevents the wearer's horn from growing back, and blocks the wolf just like an ounckse. As with any cornectomy, a horncap can be hidden within a realistic fake horn.

Lady: the rank of a vampony who is owned by a Master, but may also own lost ones (in which case the ownership is shared with their Master). With approval of their Master, Ladies may choose to be called by a similar title that does not sound 'overly dominant' (e.g., 'Gent' for a male Lady). A Lady's controller is the only vampony who need not call her by her title (see cunt for more details). A Lady may control, but not own, another Lady (with both Masters' approval). See materials for details on how to spot a Lady.

letting out the wolf: the act of transformation vamponies undergo when they embrace the wolf and allow it to emerge physically, or when un-turned ponies taste the wolf. They lose control of their bodies and minds, becoming incredibly feral and sex-crazed, and gain species-specific abilities (see bloodhorn, darkhoof, fractal, horagon, nightblood, nightborn, voidmare, and wildmane). They also gain access to a vomeronasal sense called the snarl, and their thirst for sapient blood increases. Even while blocking the wolf, the basic vampony abilities of enhanced hearing, enhanced smell, fangs, and prehensile tongue can be let out (as well as red, slitted irises), although that also reduces their ability to think rationally. Note that vamponies must let out the wolf regularly (about once a week, per Cadance) or they start to lose the ability to think rationally entirely—and for those who can't hold the wolf, letting out the wolf requires being shackled (see the wolf).

losing one's marbles: the process of becoming a proper vampony. For adults, this involves being reaped, being turned, and being broken, generally in that order. For vampony foals, this involves being reaped and tasting the wolf three times (see vampony foals for more information).

lost one: the rank of a vampony who isn't a Master or Lady. This is the lowest of the three ranks. Lost ones are not permitted to control other ponies unless specifically ordered to do so while under direct supervision, and the other pony must also be a lost one (or a non-vampony, such as a marble). It is preferable to call them cunts (or bitches) unless the distinction is important. See materials for details on how to spot one.

marble: a pony scheduled to be turned (a new follower of the Order of Spring). Marbles may be called cunts prior to being turned if reaping determines them to be a Lady or lost one.

Master: the rank of a vampony who is owned by nopony else. Masters are considered to be their own owners. Only Masters are permitted to hold the wolf and use the stance. They may choose to be called by whatever title they prefer. The only baubles Masters wear are onyx earrings and (optional) onyx collars.

materials: the material that a bauble appears to be made from secretly projects information about the wearer to other vamponies, as follows.

copper: lost one

gold or white gold: Lady (1, 2)

granite: foal Lady (2, 3)

marble: an initiate not yet following the Order

semiprecious stone (4): emancipated Lady (2, 5)

silver: Lady, on the market

steel: lost one, on the market

onyx: Master

opal: emancipated lost one (5)

wood: foal lost one (3)

(1) = The white gold alloy must either appear distinct from silver, or else be embedded with obvious yellow gold as part of an abstract design (like a curved stripe in the middle of a collar). Apart from Masters who choose to wear collars (which can be whatever they please; only the onyx earrings are required), this is the only situation where a bauble may be two different colors. (Naturally, this restriction doesn't include natural color or pattern variations appearing within materials like marble, stone, or wood. This implies that silver and steel baubles will have the least amount of variation, which is intentional.)

(2) = Ladies who are not on the market are permitted to have abstract designs carved into their baubles to allow them some uniqueness, as long as the designs are smooth and not overly intricate. Rarity says they need to feel smooth to the hoof: they can't be carved with so much detail that they gain a rough texture, and they can't feature gemstones or anything that isn't the material itself. For all kinds of lost ones and for Ladies on the market, designs are completely smooth and plain (intentionally). Some mild amount of variation is permissible, however. For example, a steel collar could have a slightly raised edge, or be burnished in a certain way, or the furry lining could be a custom color (usually done to match the vampony's coat). In all cases, the vampony's Master must approve.

(3) = Vampony foals may only wear granite or wood, even if they are emancipated. They aren't permitted to be on the market.

(4) = These must be brightly-colored (e.g. carnelian, jade, lapis) and composed of only one type of stone.

(5) = Vamponies can't be on the market while they are emancipated.

mudblood: the syrupy sanguine goo produced within the splits of a darkhoof. Physical contact with roughly one milliliter of it causes a pony to taste the wolf. Mudblood has a strong flavor similar to cinnamon, lime, and MSG, and it feels intoxicating to touch or taste even when experienced in trace amounts (i.e. without tasting the wolf).

nick: this isn't an official thing yet, but it refers to cutesy nicknames vamponies have started calling each other when they're letting out the wolf. A few obvious examples I've been given (you can probably guess) include: Slutterbat, Painbat Gash (pending approval, since she's still on the loose), Despairity, Kinky Cry, Princest Preydance, Gash Entry (I'll admit, that one actually makes me laugh), and Princest Lunatic. (Sorry, I will NOT list my suggested name here—I still have my dignity intact, for now.)

nightblood: a pegacorn vampony, like Princess Cadance (and hopefully, never like Princess Twilight Sparkle). Nightbloods have the vampony traits of both bloodhorns and nightborns, and a single bauble that blocks the wolf for either kind will block the wolf for a nightblood.

nightborn: a pegasus vampony, like Fluttershy. Not to be confused with nightwings (see nightwing for more). When letting out the wolf, a nightborn's ears poof up slightly, their wings change from birdlike to batlike, their pupils become slitted, and they gain echolocation. They also have a low-light vision they can turn on and off, which makes their eyes glow slightly and allows them to see infrared signatures. If they are also nightwings (instead of normal pegasi), letting out the wolf will give them the dexterity and speed of a pegasus and an improved sense of smell (as well as the traits common to all vamponies, like further enhancement to their senses). Shredders and wingclips can be worn by a nightborn to block the wolf.

nightwing: a former member of Princess Luna's Night Guard, or any descendant with the 'bat-pony' phenotype. Nightwings are very rare. Nightwings are not as dexterous or fast as pegasi and have a limited sense of smell, but retain the bat wings, ear tufts, fangs, slitted pupils, echolocation, enhanced hearing, and low-light vision of a nightborn. Nightwings who are also vamponies retain these abilities even when not letting out the wolf, and when letting out the wolf they also gain the dexterity and speed of a 'normal' pegasus. You can tell the difference between a nightwing and a nightborn who is letting out the wolf because the nightborn will have red irises, and appear to be feral (even while holding the wolf, as this takes a lot of concentration).

on the market: this refers to Ladies and cunts who do not currently have a Master. Ladies are not permitted to own cunts on the market, which implies that a pony on the market has no owner. This is usually undesirable, but occasionally necessary due to the scarcity of Masters and situations where a cunt is dropped from ownership by their Master (which is the only way an owned vampony can go on the market). Vamponies broadcast being on the market by using different materials for their baubles. While on the market, no permission is necessary for Masters or Ladies to control them, except that a Lady will need their own Master's permission to control another Lady who is on the market. Note that emancipated ponies and vampony foals are not permitted to be on the market (they must be exchanged directly from Master to Master).

Order of Spring, the: usually just referred to as 'the Order', this is the philosophy, social structure, and extreme biological drive which underlies budding vampony culture. It isn't an organization as much as it is a way of thinking and acting that underlies vampony motivations. You don't 'join' the Order, you 'follow' it, in other words.

ounckse: pronounced OONK-say, this bauble is a toroidal double helix made from cold-wrought iron. Another material is inserted as a ring within the helix to mark a pony's rank. Wearing an ounckse disables a unicorn's ability to cast magic, and it also blocks the wolf. It doesn't prevent the use of dark magic, but only the highest level unicorns can use dark magic spells so this almost never matters. The emancipated version of an ounckse is simply made from the usual bauble material instead of cold-wrought iron, in which case it can block the wolf without inhibiting magic.

owning: to completely control a pony for the long-term. A pony can only be owned by a single pony at any given time, except that Masters always own their Ladies' owned cunts as well (ownership is transitive).

rank: the social standing of a vampony as determined by reaping. There are only three levels. Master is the highest level, Lady is the middle level, and lost one is the lowest level. Vampony foals (who remain un-broken—see vampony foals for more) may only hold the latter two ranks. Emancipation has no effect on a vampony's rank.

reap: to determine the rank of a marble, usually through the use of a magic spell.

shredder: a more disabling version of wingclip with an attached sieve that shreds the wearer's primary feathers, preventing flight entirely (gliding is still possible, but requires a lot of awkward flapping). When a pony such as a nightblood is letting out the wolf, the missing primaries correspond to a shredded plagiopatagium (the largest section of skin of a bat's wing that attaches to the side of the pony). For nightbloods who are also nightwings, shredders are modified to shred the skin of the wing (which, apparently, regenerates slowly even if they aren't vamponies). See wingclip for additional information.

sister-bitch: either of two or more vamponies of the same rank who are controlled by the same pony. This address is relative, meaning the phrase "Rarity is Cadance's sister-bitch" makes sense (if they share a controller and rank), and mutual sister-bitches may call each other by the title; but nopony else will directly call them that.

snarl, the: a vomeronasal sense (the ability to detect and respond to pony pheromones, which by all rights shouldn't even exist) that vamponies unlock by letting out the wolf. The name comes from the fact that the receptors are found along the upper gum line, so a vampony using it appears to be snarling or sneering.

split: each of the three pieces of a darkhoof's lower leg when it splits into three parts. Each split is multi-jointed and highly dexterous. The interior of the leg oozes mudblood.

stain, the: the part of the brain destroyed by a Breakstone. (I'm afraid to ask more about this at the moment. I just don't want to know.)

stance, the: the awkward-looking two-legged posture taught to Masters, which only Masters are permitted to use.

tasting the wolf: the act of an un-turned pony letting out the wolf by coming into direct contact with mudblood. This is frequently done for vampony foals, who are not turned prior to their cute-ceañera. Foals must taste the wolf three times before they can be considered vamponies. Tasting the wolf may also be used to convince marbles to willingly be turned.

turning: the process of infecting somepony with the vampony mutation, which is mediated in part by a magical bacterium. Tasting the wolf does not count as turning. This is slightly confusing because vampony foals are neither turned nor broken until their cute-ceañera, and instead must be reaped (just as adults are) and taste the wolf three times to become vamponies.

vampony: a pony who has lost their marbles, through being reaped, turned, and broken, generally in that order. Vampony foals only need to be reaped and taste the wolf three times to lose their marbles (see vampony foals for more). Vamponies who let out the wolf by a tiny amount (which any vampony can do, even while blocking the wolf) have access to heightened senses of hearing and smell, an overpowered sex drive, retractable fangs, and a long, prehensile tongue (and red, slitted irises). When fully letting out the wolf, vamponies gain access to additional abilities (see letting out the wolf for more). They are naturally noctural, but they can maintain a diurnal cycle instead. They eat and drink normally, but they need to drink a sapient being's blood (other vamponies' blood works) to remain healthy, and their own blood will not refresh them. So if a vampony is isolated from other ponies for longer than a day or two, they begin to weaken (which explains how I was able to overpower Rainbat Dash). Drinking blood also intoxicates them a great deal. Their only other weakness I'm aware of is the wolf itself, but it's a significant impairment (see the wolf for more).

vampony foals: foals are neither turned nor broken until their cute-ceañera, but they can still become vamponies. Instead of the normal method, foals lose their marbles by being reaped and tasting the wolf three times prior to their cute-ceañera. Vampony foals are not considered fixed (even though they're not yet broken) because the stain is mostly absent if a foal tastes the wolf prior to their cute-ceañera (according to Cadance, but this makes no biological sense). The only social differences are that foals must taste the wolf in order to let out the wolf, and they are not yet permitted to be Masters. Foals reaped as Masters are considered Ladies until they earn their mark, except that they are rarely referred to as cunts by their Masters. Because they haven't yet been turned, they lack the weaknesses of adult vamponies.

voidmare: a (full) alicorn vampony, of which Princess Luna is the only current example (hopefully ever, because if Celestia becomes one we're all doomed). They have vampony traits of all three common pony species, and the wolf can be blocked by a single disabling bauble of any of those types.

wildmane: a zebra vampony. Wildmanes have prehensile, stretchy hair throughout their manes and tails. Rarity isn't certain how to block the wolf for wildmanes yet, but based on information from Zecora, she suspects a tight dock ring would do the trick.

wingclip: a heavy bauble which blocks the wolf in pegasi by pinning together part of the wing's alula. The weight slows flight and makes flying a workout. The emancipated version of this bauble is lightweight and barely felt.

wolf, the: the overpowering sexual and self-expressive drive all vamponies experience. The longer a vampony goes without letting out the wolf, the harder it is for them to think clearly (Cadance says once a week is a good minimum guideline). Blocking the wolf does nothing to help with this. When a vampony does fully let out the wolf, unless they can hold the wolf they lose complete control of their body and mind and must be shackled for safety. Even Masters who are permitted to hold the wolf are barely able to control themselves. Allowing any of the wolf to come out (even the parts that can't be blocked, like enhanced senses and fangs—see letting out the wolf) makes it harder for the vampony to think rationally. This is why so many stupid mistakes have been made by the vamponies so far. See also tasting the wolf.

yoked: a relationship between owner and cunt, or between any two cunts who are owned by the same Master (long-term sister-bitches).
