Vasel is the latest in the lines of assistants of Erstam the Mad Mage on Serpent Isle. However, despite looking rather strange, he is smart enough to avoid the fate of the previous assistants. After arriving at the Isles of the Mad Mage in Ultima VII Part Two, the Avatar first talked to Erstam. The mage wasn't very cooperative, by Vasel babbled something about teleportation. So the Avatar talked to Vasel.
