A mouse-like monster that lives in sewers. They can be found all over, and are resented as they chew on everything and are carriers of disease. Though not particularly strong on its own, since they usually act in groups, they can be quite a challenge for anyone who comes across them. Towns and villages have taken countermeasures to combat them, but thanks to their incredible reproductive abilities, their numbers are hard to keep in check.
As a summoned, template, creature, this creature has several changes. Anything noted with  is what it gains from the template associated with the summoners’ alignment. Divine is always listed first, and Unholy afterwards.
