Masque of the Jade Horror

This book was announced, and at least partially written, but cancelled at the end of the 3e Ravenloft line. It was to detail a new Masque, related in some way to MotRD, but with a Far East influence. In the Ravenloft Player's Handbook, it is hinted at, though with the name Masque of the Jade Dragon. Comments from one of the authors indicate that the final title was changed to Masque of the Jade Horror.
