Glush

Background
While not much is know about Glush (The Defiler), Aegon revealed that during his time in the Molten River Clan, Glush and his father had not got on at all. Glush eventually grew to follow Agronak instead.

Interactions With Mystic Obscura
Commanded by Agronak, Glush led a skirmish between the cities of Luskan and Mirabar. They killed an entire village on the way, all except for one surviving tiefling, Emmalee Forester.

Aegon eventually found Glush, and the group fought. Glush sacrificed his life to kill Aegon, releasing a necrotic bomb that wounded the party and killed Emmalee.
