Ultima Codex:Canon policy

Canonicity of various facts related to the Ultima series is often questioned. For most purposes, the "canon" consists of the material from games that were officially sanctioned by Richard Garriott, and single-player Ultima games and Ultima Online form a separate canon and timeline.

However, several parts of the canon are highly controversial. Ultima IX in particular has many contradictions with other games, and fans consider many "new" facts somewhat outlandish. How one regards this information is up to the person in question; one might respect Garriott's views, or just apply the parts that make sense and don't contradict previous parts.

The following list is based on Hacki's Nitpicking Rules.

Ultima canon

 * All of the mainline games and their official remakes: Ultima I, Ultima II, Ultima III, Ultima IV, Ultima V, Ultima VI, Ultima VII: The Black Gate, Ultima VII Part Two: Serpent Isle, Ultima VIII and Ultima IX.
 * All of the expansion disks: Ultima VII: Forge of Virtue, Ultima VII Part Two: The Silver Seed (and U8 Speech Pack, which doesn't really add or detract any information)
 * Underworld series: Ultima Underworld I and Ultima Underworld II
 * Worlds of Ultima series: Savage Empire and Martian Dreams
 * All of the manuals of the aforementioned games and expansions
 * All of the trinkets and cloth maps of these games
 * All separately released publications, such as hint books

Ultima Online canon

 * Ultima Online and its various expansions
 * Cloth maps, manuals, etc...

Non-canonical material

 * Akalabeth: Ties to mainline Ultimas are weak at best.
 * Runes of Virtue series
 * Escape from Mt. Drash: Produced without Garriott's approval.
 * To lesser extent, the console ports of the mainline games, where they deviate significantly from the original computer versions. (for example, the drastic plot changes of SNES version of Ultima VII...)
 * Unused material produced by developers: It's difficult to assess what material represents the final artistic vision of the creators.
 * Fan-created content of all kinds (though it may constitute fanon of its own)
