The rain slapped my window, trickling down the pane. Lightning lit up the sky like wrath of a higher plane, thunder beating the wind savagely. I turned away from the display of nature's fury, stepping out of the parlor into the dimly lit laboratory. A grin broke across my face as I turned the gaze of my lamp onto the experiment. His eyes winced from the light, then as he adjusted, his eyes widened in fear. He squirmed as I drew the prong from the fireplace in the corner of the room. I hissed a satanic tone, calling my devils to me. The chittering beasts, reddish-pink and small in stature, skinny, narrow beings with horned heads and pointed tails, skittered from every nook and cranny, swarming about the lab table. It was time to begin our work for the night.
The experiment cried out again and again, his voice muffled by a gag. His body was scarred heavily after the first few hours, and his back bled profusely. I lost control of myself, as I often do late into my work at night, lashing him harder and harder, infusing my magic into my strikes, cackling uncontrollably. The devils laughed a hideous chuckle, circling the table and poking at the experiment with their talons. I could feel nothing but my uncontained rage and the magic coursing through my blood. That was the moment the inquisitors burst in.
I heard the door slam open, and I turned to see the white-clad, rain soaked, crusaders smash their way through the door, swords drawn. One held a smoky wisp of holy magic in his hand, the other a holy collar of their deity, Avacyn.
"You, Tibalt. You are accused of torture, resistance of the law, and abduction, among other things."
I'd heard talk that the archangel herself would soon return, but I had no such belief. Regardless, the two inquisitors advanced, eyes widening as they saw the mess of a man the experiment had become and my devils. The one with the magic cast a spell, and I felt myself tearing from existence. I struggled to hold onto consciousness as my devils vaporized left and right. It was finally time to use the spell, whether I ever truly knew I would need it or not.
I regained composure, glaring at the inquisitors with a sadistic smile.
"I'll see you in hell, bastards," I grinned, and I screamed the incantation I learned from the devils. The pain I felt was incomparable. I had tortured people for much of my life, and now I felt the pain of each person I'd tortured, many of which I killed. I roared with the agony of dozens, hundreds, even, of people. I convulsed wildly, my vision blurring. This was it; my spark was igniting and now I could travel through the multiverse. The inquisitors turned and fled as my flesh reddened to the color of dried blood and horns sprouted from my forehead. I had new blood coursing through my veins, the blood of a devil.
I vanished from my house in a burst of sulfurous flame, and I was gone. I have no memory of the next few seconds, but I woke up on a different plane of existence.
