Selvyn's Tower

Selvyn's Tower is the tower of the dark mage of the same name, Selvyn, located west of the Serpent's Spine mountains. It serves as his laboratory, home and storage room. However, it is completely impossible to enter the tower from the outside, as Selvyn has made sure, that entrance is only possible with magical means. And should an intruder manage to do this, his Ghost Guard would attack the intruder at once.

The Avatar learned of the tower after killing Selvyn in Ultima VII. The mage dared the hero in his last will to manage to enter his tower. Finding a teleporter mirror in the hideout, the Avatar managed to enter and, after destroying the guard, looted the tower for useful equipment.

Trivia

 * Selvyn is quite vain, the tower actually has a sign proclaiming it to be "Selvyn's Tower".
 * The exact coordinates are 8°N 51°W.
 * There are two ways to enter the tower. Either with the teleporter mirror, or by walking at the northern wall, until the roof is turned off by the engine, allowing the usage of the spell Telekinesis to flip the switch.
