Contracts

Contracts are mystical pacts struck between creatures of Fae and embodiments of natural forces, that enable Changelings who possess them to tap into the powers of the force with which the pact was struck.
There are different types of Contracts. The Common ones are available for everyone, as are the Goblin Contracts. Seeming and Court Contracts are generally tied to the Seeming or Court they are associated with.
