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. The following guidelines are based on Hacki's Nitpicking Rules, but were originally designed for the purpose of nitpicking and are not necessarily the best for an encyclopedic work. Please make changes as needed, but discuss if there's conflicting views.
