Ultima is a series of open world fantasy role-playing video games from Origin Systems Ultima was created by Richard Garriott. Electronic Arts has owned the brand since 1992. The series sold over 2 million copies by 1997. A significant series in computer game history, it is considered, alongside Wizardry and Might and Magic, to be one of the norm-establishers of the computer role-playing game genre. Several games of the series are considered seminal entries in their genre, and each installment introduced new innovations which then were widely copied by other games. The games take place for the most part in a world called Britannia; the constantly recurring hero is the Avatar, first named so in Ultima IV. They are primarily within the scope of fantasy fiction but contain science fiction elements as well. Games The main Ultima series consists of nine installments (the seventh title is divided into two parts) grouped into three trilogies, or "Ages": The Age of Darkness (Ultima I-III), The Age of Enlightenment (Ultima IV-VI), and The Age of Armageddon (Ultima VII-IX). The last is also sometimes referred to as "The Guardian Saga" after its chief antagonist. The first trilogy is set in a fantasy world named Sosaria, but during the cataclysmic events of The Age of Darkness, it is sundered and three quarters of it vanish. What is left becomes known as Britannia, a realm ruled by the benevolent Lord British, and is where the later games mostly take place. The protagonist in all the games is a resident of Earth who is called upon by Lord British to protect Sosaria and, later, Britannia from a number of dangers. Originally, the player character was referred to as "the Stranger", but by the end of Ultima IV he becomes universally known as the Avatar. Main series The Age of Darkness: Ultima I–III In Ultima I: The First Age of Darkness (1981), the Stranger is first summoned to Sosaria to defeat the evil wizard Mondain who aims to enslave it. Since Mondain possesses the Gem of Immortality, which makes him invulnerable, the Stranger locates a time machine, travels back in time to kill Mondain before he creates the Gem, and shatters the incomplete artifact. Ultima II: The Revenge of the Enchantress (1982) details Mondain's secret student and lover Minax's attempt to avenge him. When Minax launches an attack on the Stranger's homeworld of Earth, her actions cause doorways
