“ A cult's theology is binding on the god involved: it is possible for that god to believe (and <b>see</b>, just like Winston Smith in 1984) that other gods are mythical, or jumped-up demons, or failing older spirits, even while those gods actually exist and thrive and act in the cosmos, even while working against him.”
“ You realize a group of men is going right to you. The man in front has a hard determined look on his face, the two men behind follow him with some uneasiness. He stops before you, holding the handle of his sword in one hand, and slaps (choose person carefully) with leather gloves he carries in the other hand. 'Rhadagald Thinvoice, I challenge You to a duel to dea...' Stopping abruptly, he realizes this is the wrong person.”
“ When you sleep, your soul briefly returns to the place where it was created/goes to when it dies, and seeks nourishment. Everybody's soul is created with a little link (or you could say a greater entity calls it back) to that place so that it can return easily, but upon death, the soul returns via that and annihilates the link as if returns.
Also, as an added thingy, you could say the entity supplying the link, or residue of the links themselves, (whichever) is the source of all arcane power.”
