Montor

The Montors (Montor east and west) were twin cities on Sosaria, where courage was especially upheld. However, the twin cities stared to fall into ruin after the great cataclysm that formed Britannia after Ultima III, while Jhelom became the city of Courage. Finally the remaining inhabitants who didn't want to accept any other virtues beside Courage, left together with the mages of Moon and beauty-worshipers of old-Fawn for the Serpent Isle, founding the city Monitor.

This was the end of the twin cities of Montor, and by Ultima IV, every trace of their existence had vanished from the face of the world.
