 The Firvulag who dwelt in the dark and wet lowlands grew small and hardy and were naturally operant, but most were much more weakly powered and often limited to Creativity and Farsense.The divergent races were hostile to each other and together developed a highly ritualized battle-religion to formalize the war between them.When science advanced enough to allow for interstellar travel once again (by the daughter worlds), Duat was re-discovered and while the original race was shocked at the divergence of the races there from their own, it was then discovered that the torcs also worked well on most but not all the inhabitants of the daughter worlds.
