Worldships are nomadic interstellar ships, typically moving at speeds of 0.01 to 0.1, c, where relativistic effects are unimportant. Although a few late Interplanetary Age worldships were used for colonization (some of these generation ships, and are still en route), and though a few worldships are eccentric life-style choices, or peopled by paranoids and hiders, most are peopled by clades and polities that are happy to live a self-contained existence plying the distances between the stars. The resulting centuries of isolation and genetic drift mean that worldships are almost always home to unique clades and subcultures, and unique species of sophont and subsophont life.

One of the smaller empire ships of the Solar Dominion, merely 8 kilometers long and with 400,000 permanent inhabitants. It is mainly a diplomatic vessel, facilitating cultural exchange and trade in the Perseus Rift and Cygexba border. The biosphere has two different climate zones regulated using advanced chaos control and a subtle utility fog to replicate gravity. Beneath the sea the ship holds 345 bays containing extra housing, smaller crafts, museums, diplomatic mergers and nanofactories.
