Spirits

The Spirits are living, breathing, personifications of mana. When a human dies and is exposed to massive amounts of mana that mana fuses with the mana from their human body. That mana is typically ejected from the leylines as a Spirit. Since they are collections of mana they need a physical object to keep them from dissipating known as a tether. They etch their name in the ancient language into the object and store their part of them inside it, often their true form typically resembling a human after the fact. A tether must be untainted by Darkness and rich in mana, typically an object with a Rune or often a Human who has not been affected by Darkness. Each Spirit is primarily made up of one of the Four elements of Mana; Wind, Water, Fire, and Earth. They wield magic artes with ease within their element and with practice other elements can be added to boost their magic.
