Summary
Monsters were freed from the Underground. Humans accepted monsterkind, more or less. Not every human was nice about it and there are problems. Problems that only a specific monster is often called to deal with in some fashion or another.

Rumor has it that she harbors a powerful weapon, the secret to her power and the key to her downfall. A single monster, after many centuries of failure, makes it past the guards and into the room that holds the weapon, but it's not what he or anyone else was expecting...
