Uncle Vivacian

Diary of Brianna Riess
Mentioned in Diary of Brianna Riess, where Ursa Trostain refers to him as an uncle.

What we know from the House of Knowledge
The party discovered a reference to Vivacian while researching the history of Hallister Zhorn at the House of Knowledge.

Zhorn and Vivacian were friends who were both experimenting with magic, but Vivacian had a darker reputation.

He was interested in ways to live on past human existance without becoming a lich. There were rumours that he experimented with hybridising monsters.
