The Great Fey Transference

Long ago, the Fey met in a grand council to set about the proper distribution between the powers of the ancient Dryads and the Conquerors from the Stars. This council was called into being after a war and a cursing.

The conflict between the Dryads of Old and the Conquerors from the Stars had been long and grizzly. In hopes of finally bringing about peace, a Hyma Dryad princess shared with the Conquerors the secrets of nature in exchange for the Cosmic Prince's power of the special form. 

Upon discovering this exchange, the princess and prince were cursed, but not before the two had ended the war between their people. 

Now, the form the Dryads are found among the Cosmic and from the Cosmic is found among the Dryads.
