Wookieepedia, the Star Wars wiki, is widely considered the best source of canonical information about Star Wars (without referring to each individual canon source itself) to use as a reference while role-playing. When used in combination with the Jedi vs Sith wiki, it should provide a complete encyclopaedia for JvS.

In colloquial out-of-character (OOC) usage, Wookieepedia is sometimes abbrieviated to Wooki, or WP.
Jedi vs Sith UsageEdit
Wookieepedia is used as a reference source, and provides background on canon items, locations, and characters. It has been used to help resolve disputes over many canon items.
