Additional details are provided in an alphabetical listing of the crew.
Primary Characters (PCs) are the equivalent of the lead cast in a television series. They appear frequently in storylines and can always be tagged in posts.
Secondary Characters (SCs) are supporting cast. They appear occassionally in storylines, usually when a particular skill is required. These characters should only be tagged with the permission of their player. If a Primary Character can fulfill the needs of the story, it should be tagged preferentially to Secondary Characters.
Guest Characters appear rarely. They are a prestige role, such as a Fleet Admiral or a Klingon Chancellor. These characters must be tagged only with the permission of their player.
Non-Player Characters (NPCs) are recurring background characters. They provide consistency from story to story as familiar names. Any player may write for an NPC but the CO should be informed when a player does so.
