-The Realms of magic-
Magic isn't as simple as summoning fireballs or shooting lightning. No, these are living entities, powerful in their own rights. Vibrant energies you have to weave and bend to your will. And they all come from different places, different worlds.
You see the world consists not of one realm but several larger planes of existence.
Ours is the realm of mortals, earth. Aside from them there are the 9 rings that are referred to as hell and there is the four hellish plains of Gehenna. There is the 7 realms that make out different forms of 'heaven'. There is the 8 Shadows realms, placea of eternal darkness where gods go to die. Each ruled by a old forsaken god. There is the Realms of Elements, four in total. Here fires, water, air and earth are in constant shift.
There are the Fey Lands where the folklore of old have retreated to. There is the Stream, the place from which arcane magi borrow power. It is a endless torrent of raw energy that never runs dry. There are the Fields of Ulysses, where the old pantheon of the Greeks reside. There is Asgard, where the old Norse gods now sleep.
There are countless others. Each able to lend unique strengths to those that opens its doors. There is a price however. Power always has a price. One does not strike deals with the powers that be without paying their dues. Every magician have to deal with the consequences and backlashes of their choices.
Magic demands sacrifices, personal or trivial. They demand dedication and rituals. Be it carving runes into wood or making summoning circles with salt. Magic is flexible and amazing but it's also risky and wild. Some magic is gotten trough actual deals with entities such as demons and fey. These deals are the basis to contract magic.
Types of magic
Trough contracts with mystical being a magician may achieve great powers. Its a two way streat however. Contracts are with a price, and the contractor might find the price a bit to steep at times. A good example would be Faust, selling his soul to a devil. Envoking contract magic usually means you have to summon the power in words or symbols. Such as calling upon the fires of hell or the spirits of the dead.
: The riskiest is Arcane Purity. These are the mages that tak e from the stream. They dont have to deal with rituals or contracts. Arcane Purity is a bomb however, set to explode at any gven moment. Mages may find them self so bristling with power that they actually explode. Elemental magic form the elemental planes are also considered Arcane Purity.
Very common, mostly safe but slow. Ritual magic draws on the power of the different realms as well as surrounding energies. The results are all depending on the effort, the people and the ritual itself. Its wide spread and seen in common fashion within such religions as Haitian Voodoo.
