Cats Claw

Religion is virtually dead and rationality rules. A new technology, promising instantaneous and free travel between any city on the planet, and allowing spaceships to spread through the galaxy in a reasonable amount of time.

The warnings, from the one remaining enclave of believers on the planet, were ignored. 2215. Hell is here.
