Recursions are unique but limited worlds hosted in the dark energy network of the Strange. Each recursion has its own laws of science, super-science, or even magic, which means that amazing things can occur within a recursion that could never happen on Earth. Many recursions were seeded into the network by the creative resonance of pure imagination (so-called “fictional leakage”), and over time these recursions have matured into places that are quite real. In some recursions, fairy creatures hang the stars at night, in others monstrous evil sleeps beneath the waves, and in a handful of recursions, Native American gods still wander. Among the many recursions created by fictional leakage there are a few created by conscious design, including the sorcerous land of Ardeyn and the shipwrecked recursion of Ruk. All told, hundreds of recursions speckle the dark energy web around Earth. Each recursion is a place of wonder, adventure, danger, and opportunity for those who can travel to them, explore them, or even create them.
