Planes are physical places on this plane of existence, little pocket dimensions that are close-by. Traveling to any of them is an arduous task only to be undertaken by the bravest. Portals to cross from a plane to another exist in various places and are sometimes marked or recorded in books.
The Middleworld: “The Mundane” it is situated at the intersection of all other planes. This is a planet that is scarred due to unknown causes.
Ethereal plane (far/near): Place where spirits dwell. Beware those that cross from the far to prey on the people who would thread the near ethereal.
Elemental Planes: Embodiment of the forces of nature. They take the shape of the four elements: fire, air, water and earth.
Feywild/dark: Home of chaotic beings. Depending on the crossing point, one may end in a very dark and dangerous place or a very vibrantly colored and disturbing landscape.
Positive Energy Plane: Plane of pure healing/positive energy, very few creatures can thread it without any consequences. Little is known about this place other than some creatures called angels inhabit it.
Negative Energy Plane: This is a place of strife, pain and desolation. It is known to have towns, castles and 7 rulers. People will try and thread this place when desperate to obtain something they must absolutely have.
The Plane beyond the Veil: Separate temples dedicated to each of the Gods. Crossing towards it is only possible with the authorization of the ones who inhabit it. They may project their voices and guide their followers.
Beyond the Planes of the Middleworld: The Space Beyond is unknown. Humans claim to hear a note being sang coming from out there.
Teleportation: The bending of space in the Middleworld leave a trace in their wake for a few hours. Good arcanists and some Plane-touched are able to retrace where the other end of that portal leads to.
Moons: There are a total of 5 moons. Four of them have been measured being of similar size, the last and furthest one is thought to be significantly larger than the other ones
