Despite the logical conclusion that the gnaw marks were probably just from rats, Regar begins to imagine something more. A transmutation spell of such horror, it would likely be associated with something worse that necromancy! A transmutation spell that turns people into rats... No! Rat swarms! And then driven crazy by such a transformation, the swarm wouldst attack itself! Rat tearing at rat, a horrific squeaking mess- Oh who was he kidding, his imagination was getting carried away.
"Well, i'm done here. Maybe we should move on? Kill some more stinky goblins or some giant bats perhaps...." Regar pauses. "Or, befriend the bats! Yeah, then WE could have flying bat mounts... No wait... Never mind, i'm afraid of heights." With that, Regar stands at the exit, ready to continue and continues his mapping process.
