Marsor's Isle

Description
Marsor's Isle is a small uninhabited island which appeared during the time of Ultima IV and Ultima V. Initially home to the vineyards of the wine merchant Marsor, the island was otherwise unremarkable, and had disappeared from the Great Sea by the time of Ultima VI.

Ultima V: Lazarus
In Ultima V: Lazarus, a large brood of dragons had taken up residence on the island, using it to rear there young and as a storehouse for the vast array of gold and magic equipment they had accumulated.

The Ultima 6 Project
In the Ultima 6 Project, the island no longer is uninhabited. The evil mage Lorcan has made it his home, where he conducts the darkest experiments, guarded by his faithful zombies. A huge pile of human remains sits as proof of his cruelty and his ambition is no less than creating the return of the dreaded Mondain himself. The Avatar has need to visit this dark place for two different spells, one for restoring hearing to the deaf (an accidential product of Lorcan's experiments) and the very dark Anju Sermani spell.
