Mondain

Mondain is a powerful enchanter responsible for numerous evils during the early ages of Sosaria, clashing with the young knight, British during the events of Akalabeth and eventually meeting his end at the hands of the Stranger in Ultima I

Biography
Mondain was the second born son of the wizard Wolfgang, the king of an unknown land of ancient Sosaria. Little about Mondain's childhood and formative events that may have shaped his early life are known, and his brother's name has never been uncovered. Whatever his circumstances, Mondain grew into a severely troubled, albeit magically talented youth, subject to frequent fits of rage and depression. By the age of fifteen, his father observed that he had taken to killing animals as a means of coping with whatever ill humors plagued him, finding consolation in his seeming power over life and death. Concerned with this sociopathic behavior, Wolfgang insisted that Mondain take a year away from his magical studies to be tutored by monks at a local abbey, hoping that this intervention would instill virtue and compassion within the violent youth. As a reward for completing such an education, the king promised his son a magical ruby gem, capable of harnessing the power of the sun.

Impatient for power and jealous of his brother's birthright, Mondain slew his father the night after this ultimatum was issued. Over a span of time never specified, he turned the magic within the gem upon itself, twisting it into an artifact of darkness. The ill magics now woven into this black Gem of Immortality helped to ensure Mondain's desire to live forever, and he was thus able to release his wrath upon the land, allying himself with all manner of evil beings and setting them upon the people of Sosaria. At some point in time before the gem's final completion, Mondain took on as apprentice a young girl named Minax, who eventually grew to become his paramour and co-author of many of his evils. The couple's eventually progeny came in the form of a daemonic construct known as Exodus, which lay dormant under the sea for decades following its "parents" demise.

In a reality perhaps never fully realized, Mondain's terrors assaulted the Sosarians for over a millennium, with their creator eventually seeking allies amongst the heavens themselves, creating dark compacts with savage travelers from the stars. In spite of this seeming stranglehold over the realm, the mage did meet with one early defeat in his skirmishes against the kingdom of Akalabeth, having his forces routed by the young champion, British of the White Light, a Terran youth who was granted a kingship over half of the land for his valor.

Eventually, British proved instrumental in the defeat of the sorcerer, summoning a champion from his homeland through means of a magical amulet. This hero, known to history as the Stranger, was able to obtain the four gems secreted away by the feuding kings of Sosaria and with them, activate a machine which enabled the hero to navigate time and space to arrive at the moment before Mondain's gem was completed. Shattering the artifact, the Stranger robbed the enchanter of his immortality, and thereafter slew him.

Existence After Death
After his demise, the Gargish race managed to remove Mondain's spirit from its place in the Void, and placed his consciousness it into their Shrine of Control, convinced that his intense drive to master the world around him made the sorcerer a fitting representation of the Principle. It was here, upon the gargoyle homelands, that the Stranger, now the Avatar, found him in Ultima VI. In this meeting, the mage explained to the hero that he now regretted his actions, having had time to understand that in his insane desire to control the world around him, he had lost control over himself. He explained to the Avatar that without self-control as a foundation, striving to control anything proves fruitless, and imparted to the hero the mantra of Control: "Un."

It is not known what became of Mondain after this encounter, as the gargoyle's lands were eventually destroyed, and it is unclear if the altar to Control later established on Terfin was the original which held the wizard Mondain or a facsimile. However, it is known that Exodus, whose psyche was similarly enshrined by the gargoyles, appeared to make an attempt to reunite itself with the Dark Core during the events of Ultima VII, implying that the construct's spirit was free from constraint. It may be that after the destruction of the world of the gargoyles, Mondain's was likewise at liberty to wander.

Legacy
Mondain's evil did not end with his death. In addition to both Minax and Exodus attempting to avenge him in the years to come, the shattering of the Gem of Immortality had powerful ramifications for the lands of Sosaria, and may have been responsible for the disappearance of three of its major continents - at least one of which was later discovered to have reformed as a world in its own right. . In addition to this, shards of the broken gem still existed deep within the bowels of the earth, carrying with them fragments of the evil they once represented. Many years later, the ship-wrecked crew of the Ararat came across three of these shards, which transformed three of their lot into the malevolent Shadowlords - dark beings who would come to imprison the, then established, Lord British and corrupt his appointed regent.

In addition to this, the magician's own skull proved an artifact of dark power, as Mondain had placed a magical matrix within it, allowing it to be used to kill numerous victims even long after his death. Any who invoked such dread magics, however, were stripped of the virtues within them for this wicked act. During the early Age of Enlightenment, this thing of evil could be found at the bottom of the Great Sea between three volcanoes, from which the isle of Terfin would eventually arise.

Trivia

 * Mondain appears in Seiji Tanaka's manga re-imagining of Ultima III, in which he appears as one of the lieutenants of Exodus, along with Minax. Presumably, the hellspawn resurrected them after their original respective defeats, which are mentioned in the comic.
 * In Ultima IV, it is possible for the Stranger to destroy the Skull of Mondain by casting it into the flames of the Abyss. It is uncertain as to whether or not this action is canonical, however. While the scholar, Erethian implies that the hero did, in fact, drop the skull into the volcano's maw, the skull itself (or something purporting to be it) later shows up as a curiosity in Britain's museum in Ultima IX.
 * Mondain compiled a tome known as the Black Compendium with assistance from Minax and Exodus. The book gives elaborate instructions on how to prolong ones life through dark ritual magic.
