From the introduction:
Dreams are not only the mind’s way of easing its burdens; dreams are also sources of ancient knowledge and mystic power. There are some individuals within the multiverse capable of pilfering dreams and selling those dreams to those who can meet their price. It has come to your attention that at night, in the market square of Dhoz-Kam, strange baubles can be purchased for the right fee. Among the bizarre merchants who ply their trade in the bazaar is a fellow who claims to be a Dream Trader. He possesses an extraordinary dream- the dream of a god. Those interested are undoubtedly sorcerers, the power mad and explorers of the Moonbeam roads who would dare to experience the dream of a god and obtain the extraordinary knowledge of a god's dream.
