www.rpgnow.com might be of interest. It is in the d20 fantasy sourcebook section. I haven't seen it but here is the product blurb:
41-pages by J. Lloyd and James Gustafson
Prepare for your new lords.
Can you stand toe-to-toe against these warriors of unnatural speed? Are you able to break the will of these indomitable creatures? Will your magic succor you in these darkest times?
No, of course not. You are the slave and they are the masters.
Inside, you will find:
Four new base classes: insightful Oji, Rojin shadows, Ruhak scouts, and Wudu masters. More than 12 pages worth of details!
Two intimidating prestige classes: Cimadhi (followers of the Chant) and Nijin (goy monks).
The new Frenzied monster template, which goy elders are doomed to suffer!
Twenty new feats, eleven of which are the symbiotic type, allowing empathically linked companions to become more than mere servants.
Eight new weapons and one new suit of armor. Seven pages dedicated to goy dress, psychology, society, and reputation.
