Earth

General Information
Earth, also known as Midgard, Terra, Heimat and 'the World' is the home of Humanity. It is the third planet from the star SOL. SOL and it's planets reside in the outer arm region of the Milky Way Galaxy and is part of the galactic neighborhood "Enthimma" wich includes 37 other solar systems.

Cosmogonically, Earth is part of a region known as Narlled where the branches Arrisen (are-rise-en) of Yggdrasil and Eerisen (ear-rise-en) of Yeodoor cross.

Brief History
Earth and Equestria used to be fairly close to each other in terms of gravitational resonance between the two universes. Humans used to interact with the ponies of Equestria on a regular basis through the gateways provided by the Yeodoor and Yggdrasil trees. As time went by and their interactions became few and far between, the humans stopped believing in Equestria. This caused the two worlds to drift farther apart. Magic faded from Earth and the Yggdrasil began to die. There were a few humans who still believed in Equestria, who knew that Unicorns Pegasi and Earth Ponies were real and who had seen with their old eyes the alicorns in all their glory.

 They built the doorway called Turoten which used the last of their magic. For the final time, they summoned their command of Bifrost and sent the Turoten to Equestria, in the hope that the Equestrians would be able to use it to reach their world again. The old magicians were able to send it to the alicorn sisters but the rift that grew between them and the advent of Nightmare Moon caused much to be lost. The Turoten was lost in Equestria for hundreds of years. Unfortunately, the Turoten could not use the Bifrost any longer. Though the magic of Equestria was strong, the worlds had grown so far apart that no bridge could span between them.

Magic
Earthlings used many forms of magic. The systems employed varied greatly, from spoken incantations to a form of magical expression through dance and motion. The system that saw the longest life, however was the Runic system. Runes were an inscribed art. Usually the spell employed would be carved into a specific medium. The type of spell, duration and placement all have a hand in determining the medium to be used.

The Common Mediums

 * Metals
 * Gold: spells of protection and travel
 * Silver: spells pertaining to health and wellness
 * Brass: enchanting objects and infusing them with energy
 * Steel: spells pertaining to fortune, destiny, luck and fate
 * Materials
 * Stone: eternal spells or enchantments that have no set expiration
 * Wood/Scrolls: temporary or one-time-use spells, also the medium for payers and well-wishes
 * Sand: Ley-spells. Sand would be used to draw massive runes that will serve as the template for a ley-spell. The spell would then be constructed of several runestones or buildings. A ceremony involving the placement of the final runestone completes the construction. See Ley.
