Deathfin Kugo

Deathfin Kugo was an early Deathfin of the Sons of Baal. He wrote the oldest Deathfin Scroll in the monastery, which may also be the oldest such scroll in existence. 
He lived so long ago that the label on his scroll case was not only written in old Kuar, but with a glyph drawn in a full triangle, rather than the open triangles adopted later.
