The Town Square
What happened in the brief moments before Athinar's death was extremely painful. Getting thrown about like a ragdoll, he was confused. How had this sickly, frail, weak mage do this? What had the power? However, any thoughts he had were shattered, as the Overlord increased the torment. In the few seconds before his physical form was destroyed, he felt nothing, every sense was overloaded.
In that moment, the world faded away, and he looked up, seeing a tether to.... himself? Then all was Void.
The Void, Thirty Years Ago.
Deep in the depths of the Void, Athinar the Void Lord floated around, amused. It appeared that the Demonic Keeper from three worlds ago had appeared, and come to the current one. He would take a vessel, and live as a mortal, without his memories. However, if he died, he would return in a more powerful form, with his memories. Let's see, which form.... ah, he'd just go with his normal one. No use in doing anything special for such a dull planet.
Seeking out a form, he shot to the planet, looking into the hearts of men. None were sufficient, though. Even this world's warlords were boring. So.... he might choose a... younger target. Finding an orphan upon the steps of a monastery, wrapped in rags, Athinar implanted his soul within the body, replacing the infant's own. Being an ancient spirit of darkness, he had no qualms, no regrets about ending the life of a month-old child. As his memories faded away, the infant's eyes flashed an impossible shade of red. This would be fun.
Back in the town, present day.
As the Keeper reformed Athinar, Sarin's memories returned to her. On this world, she was known as a paladin, servant of the Emperor. However, she was much more than that. As Athinar had come to the world, and taken a body, Sarin had become one with a young girl, joining her as she prayed to a deity. They had become a compound soul, two people in one body. It was complicated to explain, but not hard to do. Needless to say, up until this point, Sarin was more of a guardian angel, but now, she was manifest.
As this happened, she flew at Balothiss, speed doubled, and battered him with a flurry of blows from every angle. It would be nigh impossible to dodge them all, though to a half-giant such as Balothiss, they wouldn't be too grievous.
Meanwhile, Athinar awoke. Ash and green fire spinning around in a cyclone of terror, a black form could be seen in the center of the vortex. After it subsided, a man, with medium-length black hair, and shining red eyes, appeared. Clad in leather, with a sword sheathed at his hip, he looked to the warlock, and with a massive shit-eating grin on his face gave a deep, theatrical bow.
"You rang?"
