Year of founding: Unknown, presumed 2600
Type of government: Caste-based, theocratic oligarchy.
Current head of government: Unknown, but chief presentor is a doboid known as 'Deacon of Virtue'.
Member species (Have actual rights) : doboids, loc-hanae, naurits, martox.
Serf species (Slaves): msomi, lélegur, rochve, various.
Resident species (Not slaves, but have no rights): drifters, wabak.

Main
The Hegemony is the other galactic superpower of the Galaxy, a religious empire lead by an oligarchy of four and based on a two-caste system supported by slavery, with each side further separated in more castes, pluse one more category for species:
-Member species: the four founding species (although technically talking it would encompass only the doboids and the loc-hanae; the other two, sans their leaders, are slaves in all but name, although they have more rights than the serfs), with the leaders of each species forming the leading oligarchy. These are the doboids (religious leaders, politicians, psionics), loc-hanae (military officers, spec-ops, peacekeepers), naurits (naval officers, smallcraft pilots) and martox (service sector).
b]-Serf species: enslaved species that have neither freedom nor rights, but still have to fight. These species are msomi (basic infantry of slave armies), lélegur (secondary combat psionics), rochve (engineers, vehicle drivers), and slaves of multiples species, obtained from independent governments in the Milky Way (none of them belonging to the Confederation) through raiding or sophont trafficking. All of them are kept in line by neural implants, both in battle and civilian life.
-Resident species: these species (currently only two) have much more freedom than the serfs and have their own leaders, but don't engage politically and can only serve in the military. These are the drifters (marauders turned privateers and enslavers) and wabak (heavy infantry).

Military capacity
The Hegemony's takes a similar approach to the Confederation when it comes to its military. However, due to the fact that they practice slavery and do not have as much as space as their rivals, they have several key differences to make up for the latter fact:
-Assault armies also play the role of planetary defense garrisons, but many have at least a slave division defending them all times.
-Despite all doboids being psionics, the Hegemony armies don't differentiate between psionic-capable soldiers and common troops.
-Slave armies: composed of most of the Hegemony's 'member' species, these divisions of forced conscripts are their main fighting force of the empire, slave soldiers from all backgrounds (aside from the msomi, lélegur and the rochve, many slaves come from minor empires or even the Confederation due to the Hegemony War and deals with marauders) that have no say in the matter due to the neural implants that nullify their wills. Some, however (mostly officers), volunteer themselves in a desperate attempt to raise their food rations, help their families, genuine but misplaced patriotic fervor or simply to escape the hell that is forced labor. Contrary to popular belief, and despit outnumbering assault armies, slave divisions are in fact just as trained and equipped as their 'free' counterpart, althought not motivated, and therefore are much more dangerous than the public thinks.
-Assault armies: composed entirely of loc-hanae and rochve, these divisions are sent in when the slave armies either succeed (to guard the taken territory) or are defeated (to attack the weakened enemies). They consider themselves inherently superior to slave armies despite of what was previously said about them.
-Clone army: the real elite of the basic infantry of the Hegemony, the body-encasing armor that these loc-hanae wear does little to hide the fact that they are actually vat-grown clones. With a natural lifespan of less than a decade save for exceptional individuals, their lack of personal initiative is deemed an acceptable trade-off for their total obedience to their superiors and their exceptional capacity for battle.
-Xenomorph army: ravenous hordes of bio-engineered horrors created in vats made up by little more than teeth, fangs and an instintive surge to kill. A cadre of doboids monitor and supervise the raging swarms the best they can from positions well inside the Hegemony lines. Many fringe worlds of the Confederation are still plagued by their presence due to the fact that they can reproduce, requiring either military intervention or the aid of xeno-hunters to flush them out.
-Titanic beasts: these humongous creatures) either natural lifeforms captured from Hegemonic worlds or bio-engineered monsters) are by far the most powerful and dangerous force the Hegemony can deploy on a battlefield. Due to several factors (among them the slow developing and overall rarity for natural ones and sheer cost for engineered ones) only three are deployed at a time, but since even a single one requires repeated artillery strikes, and sometimes even attacks from naval weapons to be put down the Hegemony considers it a good trade off.

(Their navy is exact to the Confederation's, but half the titans and no Colossus)

New interlude, and as promised this one's about the military of the Hegemony.

Ship sizes are mostly the same, although battleships are a full mile in length like Imperial-class Star Destroyers. Since it's an empire and not a federation all ships have one design, which in this case is the moluscoid style with purple colorations. Mmmm,a pseudo-religious empire with slave troops and smooth ships with purple hulls? Where have I seen that before?
