A World Class is a designation given by Infinity Unlimited's Penetration Service, meant to signify the level of restriction a given world has. It consists of a class rating (a letter) combined with an access rating (a number).
General Organization[]
- Open (O): Free visitation and tourism. Worldlines declared safe to enter, and available for trade, colonization, or other activity.
- Protectorate (P): Levels of trade, tourism, scientific or military assistance. Generally applied to parallels with “autochronous” populations (those native to a timeline, as opposed to Homeline colonists and their descendants). Many lower-tech Class P worlds have limited and licensed trade or tourism openings.
- Research (R): Worlds set aside for special study, but not immediately threatening. Such worldlines usually have strange physical laws or wildly variant cultures, dinosaurs or other exotic ecologies, or pre-Bronze Age human populations.
- Closed (Z) -- Worlds that pose a danger to Homeline, or to The Secret of parachronics. This class includes most hell parallels, very high-tech worldlines, the Reich parallels, and worlds with aliens, magic, or open psionics
