EarthDawn - The Age of Legends
Obrulon was an Obsidiman Nethermancer, and a former member of the Crimson Sash adventuring group. After the group split up, he retired to the outskirts of Samsara to continue following his Discipline.
When the Therans attacked Samsara, he took in Phylinius, Nazeer and Buulgath and eventually taught Buulgath the Nethermancer Discipline. He was slain by Lord Abbadon on the deck of Sky Mountain while the three escaped with Captain K’tanga.
