Lord Tomasin Gralhund was the former owner of the Gralhund Estate. His family had lived there for generations. About 25 years ago, Tomasin and his high mage Nefilphasia reportedly made a deal with devils. After that, he was not seen again.
Karlin briefly mentioned that Tomasin was the lone Gralhund after Yalah and Auron [sic].
Yalah was Tomasin's mother, and Ostryn was his grandfather. Leanne was another member of the family, with her portait hung next to Ostryn's. Based on Yalah's visage, the troupe suspected that Liona was another Gralhund, possibly Tomasin's illegitimate daughter.
