This is just theory but since the plane of prophecy it seems that time is much more powerful force in the universe...this only my theory btw.... And some hints in the terrors of thalumbra seemed to point to the fact that the gods and mortals existence are detrimental to each other but necessary if the gods are to continue to exist. It seems being forgotten is the true means to kill a god forever but..... Anashti Sul has returned but the reason was due to the fact the peacock cult kepted her memory alive.... If memories keep the gods why others have not returned yet? Zou Kunnen,Paixao,Aniquilacion,Pingyuan Diqu,Xul'Varian why they are still dead? If the glaufaye still live and remember their gods why they have not returned? If those memories from time, immemorial keep gods alive why some are yet to appear or dead? Did Zeb Found out something of this nature....it seems chronomancy is not very popular in pratice among mages why? How dangerous is?
