- Fornius Tup'arrah - Text by Charles Mosteller
Planet in the Queenus Nine system notable for its population of a clade of baseline hu quasi-hybrid vampires known as the Tan'gg DruU. Distinguishing the Tan'gg DruU from other vampire worshipping cultures is the adoption by Tan'gg DruU society of a moral high code known as the Gor'dan Thi'tsu. This code, which is rigorously adhered to by the population at large, precludes the involuntary "victimization" of newcomers to Fornius Tup'arrah. Issuing planetary edicts is the governing Bloodthane, with each edict binding upon the entire population.
