Humans (World of Tiers)

Humans in the World of Tiers Universe have created small artificial pocket universes in a megastructure shaped in the form of a huge stepped pyramid with five stages or tiers, making it effectively a multiversal megastructure. A small sun and a single moon orbit around this planet, strangely making it geocentric.

These human Lords have inherited advanced technology barely understand but have managed to use it to create novel lifeforms, and also to prevent aging or disease, making them effectively immortal.

Instantaneous travel within and between the pocket universes is achieved by the use of "gates" which seem to function as teleportation devices, or as a means of creating wormholes between different regions of spacetime.
