Timeline of the Ultima Universe

The fictional Ultima universe has quite a detailed history that has been built up in through both the games themselves, and the backstory therein. Events are dated from the foundation of the kingdom of Britannia, hence BC (Britannian Calendar). History before Britannia's founding is uncertain and vague.

This timeline includes all the canon single-player Ultima games. The timeline is derived from the events in the following games: Ultima I: The First Age of Darkness, Ultima II: Revenge of the Enchantress, Ultima III: Exodus, Ultima IV: Quest of the Avatar, Ultima V: Warriors of Destiny, Ultima VI: The False Prophet, Ultima VII: The Black Gate, Ultima VII: Forge of Virtue, Ultima VII Part Two: Serpent Isle, Ultima VIII: Pagan, Ultima IX: Ascension, Worlds of Ultima: The Savage Empire, Worlds of Ultima: Martian Dreams, Ultima Underworld: The Stygian Abyss, and Ultima Underworld II: Labyrinth of Worlds.

The timeline of the Ultima universe can be aligned with that of Earth, however for every year that passes in our world, many centuries may pass in Britannia.

The universe of Ultima Online branches off from this timeline just after the events of Ultima I, and thereafter follows an alternate continuity.

Pre-History

 * The wisps teach the Armageddon spell to a human named Zog. Zog casts Armageddon. Life ceases to exist for a long time.
 * Over 3,000 years before the founding of Britannia, the religious Cult of Truth is founded.
 * The island of Ambrosia is battered to pieces by "rocks from the sky." It is thought destroyed.
 * Humans drive the cyclops race underground.


 * The future King of Akalabeth, Wolfgang, is born.
 * Wolfgang's first son (unknown), is born. Nothing more is recorded of him.
 * Wolfgang's second son, Mondain, is born.
 * The youth British arrives in Sosaria through a blue moongate, and meets Shamino.
 * At the age of fifteen, Mondain kills his father, and takes his ruby gem.

The Age of Darkness

 * Mondain uses the ruby gem against itself, creating the Gem of Immortality. He begins vile experiments among his own followers, forming hybrid creatures such as minotaurs, goblins and  lizardmen.
 * British drives Mondain from his corner of Sosaria ("Akalabeth"), and becomes Lord British.
 * Various heroes enter the service of Lord British, ridding the local realm of monsters, and earning the title "Knight."
 * The depredations of Mondain puts the study of the arcane arts into low esteem. Various Lords of Sosaria outlaw the practice of magic.
 * Shamino becomes ruler of his own kingdom in the Lands of Danger and Despair.
 * The presence of sea monsters confirmed as the frigate Pembroke is sunk by one in plain sight of a small armada.
 * Seeking allies to continue his fight against the eight lords of Sosaria, Mondain recruits help from "starwalking monsters of unparalleled savagery."
 * Minax is born.
 * At just eleven years of age, Minax is apprenticed to Mondain.
 * While still young, Minax becomes Mondain's consort.
 * Exodus is "conceived."


 * The Stranger appears in Sosaria for the first time, entering through the moongate known as the "Siege Perilous."
 * The Stranger uses a Time Machine to step outside of natural time and penetrate Mondain's stronghold. In the ensuing battle, the Stranger shatters Mondain's Gem of Immortality and then slays Mondain. Three stray shards of the Gem are accidentally scattered.
 * The release of magic at Mondain's death causes great upheaval, rending time and space, and three quarters of the world disappears. At least some of the lands are later found to still be in reach – the Lands of Danger and Despair becomes the Serpent Isle.
 * Shortly after Mondain's death, the time doors appear in Sosaria.
 * Approximately ten years after the defeat of Mondain, Minax, now grown, begins her plans by travelling through the time doors to the era outside of time known as "Time of Legends."


 * The Stranger appears in Sosaria again.
 * The following events take place outside the normal timeline.
 * In New San Antonio, the Stranger purchases Enilno, the Quicksword, from Sentri the Swashbuckler (1990 A.D.).
 * After obtaining a spaceship from Pirate Harbour, and visiting Father Antos on Planet X, the Stranger obtains the magical Force Field Ring from an old man in New San Antonio (2112 A.D., and 1990 A.D.).
 * In the place of Legends, outside of time itself, Minax is defeated by the Stranger within the castle Shadowguard.
 * Timeline resumes normal flow.
 * Manuscript fragments are found in the wreckage of castle Shadowguard. The writings hint that Minax and Mondain had been lovers, and produced an offspring, but little more.


 * 20 years after Minax's defeat: The Isle of Fire rises from the sea as molten lava spewing from underwater volcanoes while monsters begin attacking Sosarian settlements and a pirate fleet appears at sea, sweeping all other ships of commerce before it.
 * Exodus summons the Balance Serpent (also known as the Great Earth Serpent) from its home in the Ethereal Void, and it takes position at the harbor entrance of the Isle of Fire.
 * On the Serpent Isle, the War of Imbalance breaks out.
 * A ship is found sailing abandoned, devoid of crew, with the word "Exodus" scrawled in blood on its deck.
 * Lord British commissions several people to map out the land in preparation for whatever evil onslaught Exodus is preparing.
 * The Time Lord, in the guise of the cartographer Hawkwind, discovers the functioning of the  moongates. Before he can communicate the knowledge, he is attacked and gravely wounded outside the Castle of Lord British.
 * Shamino returns from his mission of mapping the interior of Castle of Fire, on the Isle of Fire. The experience renders him temporarily insane.
 * The Stranger reappears in Sosaria, and recruits three local adventurers for aid.
 * The lost island of Ambrosia is rediscovered.
 * The Stranger consults with the Time Lord for the first time.
 * The Stranger and his companions destroy Exodus in his castle. This triggers a violent set of cataclysms that rearranges much of the land, destroying several cities in the process.
 * The final forces of evil are defeated in a vast battle on the Bloody Plains. Thousands of soldiers die on both sides in the conflict.

The Age of Enlightenment

 * Between 0 BC and 60 BC

 * The town of Magincia is destroyed by demons, presumably for the pride of its inhabitants.
 * The Stranger reappears in Britannia.
 * The Stranger retrieves the artifact known as the Skull of Mondain from a deep well in the Great Sea. The well is the original site of the Stranger's battle with Mondain, as evidenced by the three volcanic plumes nearby - caused by the three Shards. The removal of the skull causes two things to happen: a volcanic island arises (on which Blackthorn's castle was built), and the Shards are knocked loose.
 * The Stranger throws the Skull of Mondain into the Great Stygian Abyss, opening the Abyss permanently and destroying the skull.

The three Banes of Chaos, improperly contained by Batlin, break free of their captor to inhabit Dupre, Iolo, and Shamino.

 * Their pride growing with the raising of the column near Hythloth, nearly all the gargoyles leave Terfin as their chief architect Wislem constructs a magnificent magical dome beneath the sea, which they name Ambrosia. The gargoyles build a life away from humans, and take with them the Gargoyle Lens from the Royal Museum, blaming humans for the disappearance of the Codex.
 * The shepherds and farmers of New Magincia are also affected by the columns, and leave their flocks and fields in search of grander dreams elsewhere. Only Katrina, companion to the Avatar, remains.

 * The mage Nico, currently residing in Britain, leaves to rescue his brother from the people of Cove. Lord British gives the mage his Orb of the Moons.
 * The Guardian successfully enters Britannia, and begins preparations for his final conquest of the world.
 * March 19 (Vernal Equinox) - The Avatar reappears in Britannia upon the mountains of Terfin and is quickly discovered by a dragon-riding Wyrmguard. The Time Lord intervenes and teleports the hero to safety in Stonegate.
 * The domed city of Ambrosia is destroyed through the pride of the gargoyles. Their entire race is almost wiped out.
 * The rebuilt city of Skara Brae is destroyed by the Guardian.
 * In the ensuing months the Avatar neutralizes the columns of the Guardian and restores the Shrines, assisted by companion Raven. With the eight original companions assisting, the Avatar journeys to Terfin and casts the Armageddon spell to vanquish the Guardian. The potentially catastrophic effects of the spell are safely contained within the confines of the Barrier of Life, and the two foes are joined in essence as one as they ascend beyond the mortal realm.

Pagan Timeline
The timeline of Ultima VIII is distinct and incongruent with the timeline of Britannia. The events that happen during the game did not happen at the same rate of time in Britannia. When the Avatar escapes Pagan at the end of the game, an indeterminate amount of time has passed in Britannia since the Guardian delivered the Avatar to Pagan.


 * The being known as the Avatar is dropped into Pagan by the Guardian. The Avatar is rescued by a fisherman named Devon.


 * The Avatar undergoes the traditional rituals to becoming a Necromancer.


 * The Avatar becomes a Theurgist.


 * The Avatar joins the sorcerer's cabal.


 * The Avatar enters the great ethereal void and defeats the four elemental Titans of Pagan; Stratos, Hydros, Lithos and Pyros. The Avatar becomes the Titan of Ether.


 * The Avatar returns to Britannia.
