Ultima IV: Quest of the Avatar

Ultima IV: Quest of the Avatar, known as Última IV in Brazil, is an entry in the Ultima series of RPGs created by Richard Garriot at Origin Systems. It was originally released in 1985 for the Apple II computer, before being brought to the Sega Master System five years later in 1990 (the only Ultima game to be released on a Sega platform).

Ultima IV is the first in the "Age of Enlightenment" trilogy, and though references Ultima III: Exodus and prior games, knowledge of previous adventures is not strictly necessary to understand Ultima IV.

A North American release was planned and advertised, but did not materialise. The same is true for a Japanese release.
