Lands of the Dark Unknown

The Lands of the Dark Unknown were one of the original continents of old Sosaria, ruled by the Kings of the Black Dragon. The Stranger visited them on his/her quest in Ultima I to get one of the gems for the time machine. With the defeat of Mondain, Sosaria was thundered apart, and nothing was ever heard of the Lands of the Dark Unknown again.
