(Constrained) Rift-Bound Fiend

Lore
When the fiend set out in search of Lorentz, a flock of angels appeared before him. "Why are there angels here?!" the fiend wondered. But his anger had overwhelmed his ability to ponder the question any further. He flew into a violent rage, spilling angel blood left and right. In the space-time rift, the fiend had a theoretically endless amount of time to find and slaughter Lorentz, the man who had bound him, The fiend's fury knew no bounds.
