Spirit Magic

Spirit Magic is type of magic found in the Other World.

Background
Technically the term spirit magic refers to a type of magic utilized only by spirit creatures. However it seems that the term also includes magic utilized by non-human races, such as elves.

Mechanics
Though spirit magic is regarded as fantasy by humans and only originating in ancient times, spirit magic is a very live art and is still practiced. Spirit magic isn’t restricted to any one species, as even humans would be able to use it if they entered into a binding compact with a spirit. The main difficulty though is humanity’s lack of skill in speaking with spirits.

Only two species are naturally capable of spirit magic: elves and spirit creatures. Though the method in which they use spirit magic differs. Spirit magic requires a binding contract with a spirit. For elves they transfer the mana within themselves to the spirit, who turns that into magic. On the other hand spirit creatures, can directly channel spirit energy within themselves.

Abilities
Unlike the magic used by humans which require short concise spells for specific phenomena, spirit magic manipulate nature directly. However users are required to make a appeal to nature verbal to call upon the appropriate effect. And like any magical power it can be exhausted depending on a user's usage.

Simply put, this magic is about making connections to spirits:

Earth Spirit.

Fire Spirit.

Wind Spirit.

Water Spirit.

Unknown Spirit probably dead or Darkness.
