Temple Trouble

This is a little gem of a story set in Piper's Paratime Universe of almost infinite possibilities, here looking at the old religious pantheon.  The Paratime people are mining uranium, and construct a religion to divert the natives. However, a group of Paratime criminals have manipulated a cult of human sacrifice, and after the criminals win a few battles and rabbits start dying off from an imported disease (rabbits are sacred to one of the major religions), the monarchies start converting to the new god.
