Nevinyrral

Nevinyrral was a lich from Urborg. He controlled the City of Urborg, which was once at war with Bogardan. Little is known about the war, but legend states that he was outmaneuvered and the city was swallowed by a volcano that tore up from the ground directly beneath it. His last act was to use the powerful Nevinyrral's Disk to deny his enemies any of the magical trove that might survive the flames, destroying himself and most of Urborg in the process. He is also the author of the Necromancer’s Handbook, the Bible of necromancy.

Nevinyrral's name is derived from Science Fiction author Larry Niven who came up with the term Mana to denote the amount of Magic as a non-renewable resource tied to lands. In Niven's Magic Goes Away series, his protagonist The Warlock invented a spinning disc that used up and drained available mana in its vicinity as an experiment -- inspiring the designers Alpha to make Nevinyrral's Disk.
