Minax

Minax is the main villain of Ultima II, and the apprentice and lover of Mondain.

History
Minax learned the dark arts from Mondain. As Mondain unleashed havoc on the land, Minax watched him and was amazed at his power. She fell in love with him and together they created Exodus.

When the Stranger killed Mondain, Minax was still quite young and inexperienced. There was a period of a several years that was used by Minax to study powerful magic, so she could one day destroy all of Sosaria and its inhabitants.

She made her move in Ultima II. Having moved her fortress, castle Shadowguard, to the Time of Legends, she tampered with the timeline in order to destroy the world of the Stranger. She succeeded in totally altering the timeline, and Earth was destroyed in 2111 A.D. in a nuclear holocaust. At the same time, her monster hordes attacked Sosaria.

However, she had no idea that the Stranger had escaped the changes in the timeline. Traveling back to the Time of Legends, the Stranger killed Minax with the Quicksword Enilno, ending her tampering with time. After her death, all the damage done to the timeline vanished as if it had never happened.

But even death wasn't her end. The Gargoyles pulled her soul out of the Void, and fused it into the Shrine of Passion. It was there, where the Avatar found her in Ultima VI. She told him that she now regretted her wrongdoings, having had enough time to think about what she had done. She explained that passion had been the essence of her soul, but that passion knew no bounds. She wanted everything, and because of this strove to conquer all. But passion must be directed, focused. Unbridled passion, desire for all things, leads only to chaos.

Trivia

 * "Minax" is a Latin word meaning "threatening" or "ill-boding."
 * Although Minax is shown as attacking Earth in Ultima II, she is also known historically as the harbinger of Sosaria's Second Age of Darkness, implying that her influence may have affected multiple worlds.
