Let me introduce to you all Katslet Oilflames the Dimpled Talon of Man, necromancer necromancer necromancer necromancer necromancer necromancer necromancer death corpse.
Yeah, that's seven different brands of necromancy, and a suffocating interaction he got from becoming a death corpse. He originally started his adventure with his brother Zulur Oilflames, but during a desperate fight with a horde of zombies, they choked each other to death and brought each other back as revenants. After that, though, they went their separate ways. (I couldn't swap back to Zulur and they were stuck at No Quarter.) Katslet eventually took down several necromancer towers, but they weren't without cost.
Katslet's armor was reduced to scrap metal during a battle with one tower of fellow revenants, except for his steel helm and chain mail, which saved his life many times. He took many wounds that would have spelled death for a mortal, but were mere flesh wounds for a mighty undead. He lost his foot in a battle against another legendary axelord revenant who carried not one, but two slabs of necromancy, in addition to a host of other treasures.
Katslet claimed many treasures from his enemies, but he couldn't keep them all. Despite his strength, he only kept what he could wear - mostly jewelry and assorted armor, storing the rest away in keeps and temples. His most prized possessions were his bismuth bronze battle axe and steel shield, both artifacts claimed from the commander of a horde of undead that had conquered half the world.
But now, battered and beaten, Katslet missed the simple things. Life had not carried the same spice since he had died. Having learned every kind of magic he could, and with no husking dust anywhere in the world, Katslet decided to retire.
Perhaps someone else might be able to take up the mantle of the Ultimate Undead...
