Twelve of my characters are avatars of the same god, twelve empty skins worn by the Zeroth of Dawn's Beauty.
My remaining six characters are narrated as individuals, but none of them really know each other. Two of them are on the staff at the The Ivory Tower (the premier academic institution of the Shivering Isles), but one is a Senior Fellow and the other a junior assistant to the under-gardener, so it seems likely they are hardly conscious of the one another's existence.
