From the introduction:
All the worlds ended, literally broke apart, but the Heartless Princess saved the bits she could, embedding her icy city at the top of a new patchwork planet made of the fragments of the old. You are her trusted aides and servants and envoys, and today, she has a request.
Her seers have divined the location of a magical orb that will generates endless heat, very valuable in the icy city. It waits in a faraway land that is apparently lifeless. She has a way to send you to it and a way for you to send it back. Will you do it for her?
