Lost Sosaria

Worlds of Ultima: Lost Sosaria is a "Worlds of Ultima"-style spin-off of the main Ultima series of games, set to a tangent of Ultima VII. It tells the story of those companions of the Avatar who were missing without explanation after Ultima VI, as well as several other key characters from that game.

It is the creation of Kenneth Tully, and uses the Neverwinter Nights game system.

As of October 2010, development on this game has been put on hold.
