Earth

It should be clear what planet Earth is; home to mankind, in a time of technological advancement. Earth is also the home planet of Lord British and the Avatar. However, Earth itself plays a minor role in the series. It is usually only seen in the intro and end sequences of the games.

In Ultima II however, Earth is the central place of the game. Minax had manipulated the timeline, resulting in a totally changed past. In the end, Earth was destroyed by a nuclear holocaust in the year 2111 A.D.. The Stranger attempted to repair the damage to the timeline, traveling to these periods of time, which were altered by Minax's meddling:


 * Pangea - 9 million B.C.
 * 1423 B.C.
 * 1990 A.D.
 * Aftermath - 2112 A.D.

In the end, the timeline was returned to normal, and all these events had never happened, apart from the memories of the Stranger.

The only other game where Earth is part of the action is Ultima IX, as it is the first playable area of the game.
