Fang the Gargoyle

It should have been so easy, just a simple first quest after joining the adventure guild. You just needed to go explore a long abandoned church on the outskirts of town, then report on any monster activities. Slimes and giant rats are what you were told to expect. You find some slimes but no giant rats. That is odd as they love abandoned buildings. So why are they not here. It's not until you hear a predatory roar that a thought hits you. The reason might be because something is eating them.  As it turns out, a gargoyle has made its home in these ruins.
