The Wu-Keng are a Craft of mages in eastern Asia. The Wu-Keng are all born men but are raised as women, each of them bound in service to demonic patrons (possibly Yama Kings), which have given many of the Wu-Keng Demonic Investments. The Wu-Keng were bound to serve these masters for a thousand years — a term that would have expired at the very end of the twentieth century. However, after the Avatar Storm broke out, the Wu-Keng lost contact with both their demonic masters and their own Master-level mages.
