Twilight looked up as a portal opened in her library wall. She placed a bookmark in her current erotic novel just in case she needed to take care of whatever was coming from the other side. Her horn glowed for a moment as she placed a few cautionary runes outside of the line-of-sight.

"Can I help you?" she asked as a big, hulking figure strode through the aperture. It looked like some fires were blazing on the other side, but it was hard to tell more than that due to all of the smoke from the being's world.

"I are Gurg da Almighty! You have something of mine!"

Twilight's face scrunched up at the sour smell wafting off this strange being. Had he never heard of baths? Apparently not, his putrid musk was far too rancid for anything as basic as hygiene to be a part of his daily schedule.

"God are you ugly!" she observed, placing her book down to get up and study the creature. "I honestly can't see how even your mother could love a fact like that. They had to have specially engineered that physique too! There's a lack of any coherent magic anywhere on your person, so I'd presume that they somehow managed to program your stench into your genetics instead. Simply fascinating!"

"URG!!"

"Calm down," Twilight scolded, taking the stupid, lumbering form into her telekenesis in order to sit him down properly. "This should only take a few moments, if you don't mind?"

"UGG!!"

"I'll take that as a 'Yes, Twilight, you can feel free to experiment on me anytime!' I'm not very fluent in the language of Stupid, so you'll have to forgive me if I come across as too literate." Twilight kept her hooves and magic in constant motion while she rambled, carrying the thick-bodied brute down the stairs to her basement. She popped open the door to her laboratory as she continued ranting. "I'm assuming you're from the same universe as those weird Space Marines that came knocking last week?"

The ork just nodded in agreement, too lost in his own ineptitude to keep up with what Twilight was saying as she jabbed a thick needle into his neck. The first attempt to pierce the ork's thick hide failed, the needle breaking against his flesh. Twilight frowned before reaching for something a bit thicker. The second attempt went much better, and pretty soon a new substance was flowing into the beast's bloodstream.

"Now this might sting a little, but I promise it's nothing dangerous. I'm simply trying to see what the effects of anti-matter will have in your system, nothing too risky. Well, nothing too risky for me, that is."

The ork stared at her for a moment before his eyes rolled back and his body slumped over like a sack of moldy bricks. Twilight shook him for a moment before realizing that yes, Virginia, there was a Santa Claus.

"Wow, I really should learn to stop putting so much of my mana into my mixtures," she stated, stumbling a little as the sudden loss of energy hit her. She opened a nearby cabinet to fetch herself a mana crystal. Converting matter to anti-matter really took a toll out of her magic-pool, even if she was a nearly omnipotent goddess.

As the crystal drained itself of energy, Twilight took a quick swig of an alchemical potion to help replenish her nerves.  A quick sip and the slight aftertaste of berries later found the hyperactive bookworm back in fighting shape.

"Now then, it's time to take note," Twilight said, peering down at the now very dead ork that she'd been experimenting on. A quick study found that the life energy of her victim was absent. She sighed in annoyance before turning to her recording equipment.

"Today is the eighth of December, year of Celestia one thousand and two. I've finally found a test subject in whom I can experiment proceedures pertaining to the creation and destruction of life. Just as I'd suspected, the moment the subject died from critical anti-matter poisoning, his body lost all of its material life force. That proves my hypothesis that energy cannot be found in a person whose energy was depleted upon death. Simply put, you can't create energy from nothing."

Twilight lifted the body up as she continued with her monologue. A quick flick of her horn and the still form was placed back onto the workbench.

"I had hoped that anti-matter could work to negate this, but I suppose that such optimism was foolish of me. Simply put, I'd have been better off keeping the subject alive in order to simply transfer his energy rather than terminating it. As it stands, my experiment can't...my experiment can't do in good in..."

She paused for a moment, letting the tapes roll before throwing her notepad aside and slamming the table into the nearby wall with a frustrated scream. Twilight's blood was pounding in her ears as she blasted the nearby sound-recorder to bits of shattered metal.

A small pile of started but unfinished letters stood out on her desk, none of which would ever be finished. Twilight sat down with a tired sigh, picking up her quill and pen to write.

Dear Princess Celestia,

I miss you.

Twilight.
