from the What is Qalidar? web page:
While the home world in which your characters live could be any real or imagined place you want, the central assumption of this game is that Qalidar lurks beneath the surface.
Qalidar is a name for the cracks spreading out from a hole in time, and for the pits one drops into when falling through those cracks. Perhaps most famously, it refers to a starless city at the heart of the spiral where three roads named for the three gorgon sisters converge.
Qalidar is also the transcendent Storm that opens the way to this broken reality and offers the canny traveler a powerful, if dangerous, path to faraway ports and alien worlds. And beyond that Storm, if such a thing is conceivable, Qalidar is the screaming light that sears the empty plains of the Outside.
These are lost, broken worlds of toxic darkness, filled with fungus-maddened cannibals and carnivorous living crystal. The sentient beings that have learned to survive here are no better for their rationality. Less evolved minds would never be capable of such calculated cruelty. Less evolved minds would never have found a way to extend their venomous claws back into the natural world.
These interloping minds from the dark places under the universe constitute the other major component of the assumed setting. Corporations and governments are being manipulated across multiple worlds. Whether intentionally or by reckless exploitation, the universe is being altered. The player characters, as storm walkers, able to travel through the Storm, will be among the few individuals in a position to discover and combat these depredations.
