Black Wyrmsergeant Golbagh
The cleric once forsaken, now blessed by Tiamat
Black Wyrmsergeant Golbagh is a member of the Black Army of the Cult of Tiamat. He had tracked the Codex to The Fang, a backwater part of Annoril, by following the trail of Valomir, the paladin of Bahamut last known to possess the tome.
However, a group of adventurers were also after the Codex and interfered with Golbagh's plans to claim it for Tiamat. He finally defeated them with the aid of Fleshburn's offspring, a young black dragon, in the Holoroon Marsh in Deluge of 2663 CE.
