Famous fire mages in D&D?

[Quickleaf]

I'm looking to include some flame skulls in an adventure that are the undead remnants of famous named D&D mages. Any setting is fine.

So far I've found Aganazzar, Daltim, and maybe Abi-Dalzim... but what little backstory I can find on Aganazzar and Daltim paints them as heroic and not villainous figures.

EDIT: Aganazzar seems to have been slain by Red Wizards of Thay, so it's conceivable they might make him into a flameskull (perhaps if there was magical lore they hoped to get from him that wasn't in his spellbook).

Any fire mages I'm forgetting? Any sources you'd recommend looking to? Thanks!

 

[Tales and Chronicles]

There Ignus, the pyromaniac cursed wizard from Planescape:Torment
Maybe Vanifer, the tiefling prophet of Imix in Princes of the Appocalypse.
Daltim Flamefist, Pyromancer and psionic from Haalrua.
One of the many high-level firemage from the Brotherhood of the True Flame from Zakhara.

Just some I've found on the internet.
