Saul the black knight

Saul was once a king.

Background
Telgrin stole the soul of King Saul using the Jewel of Orkae, creating one of his black knights.

Behind the scenes
The black knight King Saul may be a reference to the biblical king Saul of Israel. But they are likely not one and the same being. Not unless Telgrin managed to steal his soul near the end of his life (when he committed suicide).
