List of realms
Below is a list of realms and it's inhabitants:
The main mortal plain between Vethfolnir's Tree of Life and Nott's Tree of Knowledge. Most, if not all mortal beings start out here-- from humans, satyrs, nymphs, nooks, and harpies, to giant monsters, such as werewolves, nagas, vampires, rougarous, yoxes, wyverns and more.
Sometimes referred to as the Great Tree by the mortals. It's said that souls worthy of entering the heaven of the dragon god Siguard, they must first climb the tree to the top. Vethfolnir lives at the crown, where her feathery down floats to the mortal realm and creates life. Harpies and other beings of life make the tree home.
Mirrored to the Tree of Life is the Tree of Knowledge. It hangs upside-down from Nidhogg's Lair, where souls travel along it's trunk to reach the different realms for the dead and undead. Nott lives in the tree's cradle with her shade and shadow harpy followers.
Ruled over by Knocta, the Underealm is a large prison where sinful souls serve out their time before being able to ascend to the heaven they want. Often, these souls get corrupted into demons, devils and monsters.
A prison ruled for the irredeemable souls; Lucy and her father harvest them and smash them into sludge so they hopefully turn out better in their next life. Other than Lucy and her dad, Hell is home to the goat-headed formorians.
