This monster is a huge abomination created by a powerful spellcaster named Shani for personal protection until it set itself free. Attempts of finding it and destroying it has failed and this "creature" is now in a society of fiends. It is not known how it found its way there.
Some mages suspect that Shani didn't want to destroy his "beautiful" creation so he gave him a new home.

Combat:
The hardest part of battling with this opponent is to survive his charge + full attack. The charge causes the character to be knock backed 20 ft.

Society:
Company of Fiends.
