Eons ago Lord British came unto the lands of Sosaria. Since that time it has been united under his rule as the Kingdom of Britannia and has gone through two major crises. A few years ago there were political upheavals among the city states of the kingdom. The ringleader of this political instability was Mondain, the Magician. Under his horrible rule, the people's lives were devastated. A valiant warrior was called forth from another world by Lord British. This warrior overthrew Mondain.

Britania survived the first crisis. But peace in the Kingdom of Britannia did not last long. Minax, the Witch, a disciple of Mondain, became very powerful and ruled the world of darkness. Minax had power to sway the time axis of the universe. However, a legendary hero again came to the rescue, overthrew Minax, and brought peace back to the kingdom.

Now, the Kingdom is about to face its third crisis. Rumours abound about a fiery island which has emerged in the southwestern seas. Little is known of the evil that dwells there. It is known only as Exodus.

Everywhere, Lord British’s subjects were happy and prosperous. A great cancer had been exorcised from the world body. The People were cleansed again, and there was much rejoicing in the towns. Even the Orcs had disappeared from sight after the fall of Minax’s castle, as chronicled in Ultima II. Twenty years of peace lasted. Twenty years is also the time needed for an infant to become a person.

From the ruins of Minax’s castle has come several fragments of a manuscript which hints at a dark secret. There appears to have been an unholy alliance between Mondain and his young apprentice, Minax. Something had fructified from that union, but whether that something was of Man, Monster, or Daemon, the manuscript fragments were eerily silent about. What had become of the hell-born prodigy? No clues existed.

Time passed, and the omens began to be troubled. Comets clashed across the sky and rumbles were heard deep in the ground. Then one day, in a fiery birth of molten lava, an island rose up in the middle of the ocean. None could approach it; the fire and steam were too great. Some drunken sailors claimed to have had a glimpse of the island when the steam was momentarily blown away by a strong wind. They swore that a castle existed in the middle of that inferno, but thou knows how reliable is the word of a drunken sailor.

Then, the sweet flowing rhythm of country life was shattered. Orc drums began to pulsate through the hills and mountains, and the horrible raids began. The outlying settlements all moved into the safety of the village fortresses. Shortly thereafter, a Pirate Fleet appeared suddenly, and commerce was swept from the seas. An evil power was rising in the West, and all the earth groaned to its flexing. When tales emerged that the Great Earth Serpent had risen from its long slumber at the bottom of the ocean, people began to cry that the End of the World was at hand.
