A young, angry wererat, Girrigz led a gang, the Rat’s Teat Boys, that controlled a sizable section of the city sewers. Burning with hatred for those who forced his kind to live in secret among the filth, he saw the Blood Veil as an opportunity to strike back at the hated surface dwellers.

Eries Yelloweyes warned the party about his plan and in the subsequent confrontation, the would-be wererat avenger was slain by Egan Silentall.
