Rift-Bound Fiend

Lore
The immensely powerful fiend was captured by Lorentz, who wished to study him. Lorentz put him in chains and performed a series of experiments. Being treated like a lab rat was the ultimate humiliation for a creature who also exercised separate powers in the underworld. "Someday I'll kill him," the fiend growled. The anger in his heart grew, giving him even greater strength. Eventually, he was able to break free of the chains that bound him.
