Sergen Hulmaster

Step brother of Kara Hulmaster, Sergen was adopted into the family when his father Kamoth Kastelmar married Terena Hulmaster. The Hulmasters allowed Sergen to remain a member of the family even after Kamoth's attempt to seize control of Hulburg in 1466 DR.

Sergen teamed up with his father (Kamoth) in an attempt to capture Hulburg in 1479 DR but was killed by Geran Hulmaster.
