Halder

Halder was a great wizard hailing from the city of Delzimmer in southeast Faerûn in the 14th century DR.

Halder was one of those wizards—listed among Omm Hlandrar of Halruaa, Szass Tam of Thay, Elminster of Shadowdale, and the Simbul of Aglarond—who challenged the mortal Velsharoon in his wicked plots. In turn, the arch-necromancer worked to acquire another power to destroy Halder and all the other mages who'd opposed him, ultimately achieving godhood in 1368 DR.
