Star Wars Thesaurus

"The Thesaurus lists the authority name, nicknames (including military and civilian titles), use for names, related planet (usually homeworld), political alliance/related alliance, and related characters for each Principal Character. Nicknames will appear only under the main entry, and will not have a separate entry traced to the main entry. The Thesaurus is limited to Principal Characters only, as the many minor or supporting characters frequently lacked enough descriptive information to be included in the Thesaurus categories. Occasionally a Principal Character will appear in the Other Character category for a particular novel, but are included in the Thesaurus in their capacity as Principal Characters."
