Zog

Zog was a mage that lived in Sosaria a long time before the events of the Ultima games. 700,000 years before Ultima I, Zog received the Armageddon spell from the Xorinite Wisp. He was too curious and tried it, wiping out all life on the world. He died a little later in his empty world.

His remains, the Bones of Zog, can be seen in the Museum of Britain in Ultima VI and Ultima VII.
