Raurlor

Rhaulor was the War Lord of Waterdeep. He aimed to use Waterdeep's wealth and power to create an empire in Northwest Faerûn, but was opposed by the mage Ahghairon, who had saved Waterdeep from a troll army. When Rhaulor attempted to have Ahghairon arrested, Ahghairon turned Rhaulor's sword into a snake. It bit him, poisoning him, and he died.
