Each pocket universe contains a single solar system with anywhere from one to several worlds Korda can visit. Each world requires Korda to travel to magnetic North and use a "resonance tracer" to locate the universe's "world key". The world key (each protected by a unique puzzle) stops or starts the universe's temporal flow. Each pocket universe has a unique feel to it, reflecting the personality and interests of its owner. Verdry for example, owned by a woman known for creating a philosophical movement centered on nonsense and unreality, contains a world shaped and colored like an Easter egg.
