Mondain's Fortress



The stronghold of Mondain where he first crafted his Gem of Immortality is a place only acessible to the Stranger by use of a time machine, and serves as the background of the final confrontation of Ultima I.

Description
Little is known about the location where Mondain first finished the transmutation of his father's ruby into the Gem of Immortality, but it is in this place that the sorcerer made the crucial turning point from mortal to immortal, securing forever his boundless ambition. For over a thousand years after this event, Sosaria was left to suffer the horrors of the wizard's wrath.

It was only through the intervention of the time-traveling Stranger that this momentous scene was finally breached and the wrongs of the past undone. Wherever Mondain was at the inception of his gem's completion, it was here that the hero destroyed the wizard's work, and him along with it.

Trivia

 * Until the Stranger [G]ets the gem, Mondain is rendered immortal and cannot be killed.
 * Within the fortress, the spells Create and Destroy can be used to erect or disintegrate sections of the walls, respectively (very useful to trap Mondain for the coup de grace); the Kill spell, on the other hand, has the effect of making Mondain stronger!
 * Some versions of the final confrontation in Ultima I do not have any castle walls, presenting only a black screen.
 * In the introductory sequence of Ultima Online, the stronghold of Mondain is visible, as the beginning of the game replays the events of Ultima I, that it might be revealed how the multiverse in which Ultima Online takes place was constructed.
