Fox Force Five
Bloated Female Dire Rat
The dire rats who hunt the The Sunless Citadel all descend from one monstrously swollen female, whom the goblins call Guthash (translation: Bloated One). Guthash is indeed bloated, feeding daily on a bounty of lesser vermin brought to her by her children, and supplemented by the occasional goblin or kobold.
Guthash is twice the size of a regular dire rat (6 feet long) and is responsible for the death of (forgot name, will fix later), Analise Cloudcroft’s missing cousin. Vengeance was served with the help of the Companions.
