Intelligent Rodents. While zoogs seem little more than a pest to some, they possess a devious intelligence and a willingness to scheme to their advantage. Their ability to plot and communicate makes them much more dangerous than ordinary rodents. They are willing servants of the Demon Lord of Rats and the Lord of Ghouls. They are prone to serving dark gods of the Void and Outer Darkness and are very willing to steal, spy, and nibble away ancient bonds and seals as directed by evil wizards, clerics, or monsters.
