Sphaera is an Earthlike planet tucked in an unremarkable G-type star system somewhere in galactic quadrant 4 of the Milky Way. It would be practically identical to any other terraformed world if not for its incredibly high sophont diversity. A staggering 27 species of intelligent beings inhabit Sphaera -the result of ancient science.
The universe containing Sphaera and its fellow inhabited worlds is akin to our own save one fundamental difference: the embedding of magic within the very laws of physics. This world's arcane power is ascribed to a unique class of quanta that comprise the psi force, allowing organic life to tamper with the machinations of the other four forces at the fair price of metabolism.
