Melyria uses Great Wheel cosmology used in DnD as the foundation of how the multiverse works. Description of other planes described here are a combination of DnD-lore, inspirations from outside and my own ideas.
Melyria is a custom roleplay setting made to work with Dungeons & Dragons 5th Edition by Tiirikka and friends.
Melyria draws is inspiration from several Dungeons & Dragons settings and their lore, mainly from Forgotten Realms.
Dungeons & Dragons belong to Wizards of the Coast and I claim no ownership of it.
Melyria and it's quirks belong to me and getting inspired is very much allowed and credits appreciated!
