S is for Stolas

The mostly unassuming looking fiend Stolas is actually a high prince of Hell. A wise noble, he is extremely knowledgeable in astronomy, botany and herbology, and the value of precious stones.  He is a close friend of Justuscias. The pair often wander in mortal forests. Perhaps due to their shared Strigiformes appearance, he despised Kandras.
