The Sanguine Harvest
A number of divine entities whose existence is not entirely of this world are credited with rulership over aspects of mortal life.
Humans historically believe in the pantheon of Olympus, in Verdinium and across the republic mortals give thanks to Athena for wisdom, to Ares for martial prowess et cetera.
The Dwarves offer up their worship to the Aesir and the Vanir; the otherworldly tribes to whom the dwarves credit their existence and prosperity.
Elves of the world consider Lorthekû, the Tree of Life to be their primary deity, although they treat all tree spirits with reverence.
