Nilpont, from Ultima Underworld
Nilpont is a mage of the Seers of the Moonstone.
The Avatar met him in Ultima Underworld I on the sixth level of the Abyss. Nilpont told the Avatar of a mighty Golem on their level, who was waiting for warriors to test their strength on him, talking of how in the past it was used by the Knights of the Crux Ansata to steel themselves. Nilpont added that the Valor-Golem was rumored to have a magic treasure as a price for winning.
