The mortal servants of Cyphus have formed a number of small orders dedicated to Cyphus.  Most of these are reserved in their dealings with people, preferring to remain aloof from those they tend after death.  Many serve as morticians of a sort, although nothing extensive is done to the interior of a corpse. 
A few orders have become more influential outside of the ceremonies of death.  The largest of these is the Thanatosian Order, which is dedicated to actively fighting the Unlife and its manifestations.  Chapters of this order can be found throughout the Riverlands.  There are two Merochasan chapters (one located near Tulccas, the other in Brailas) and three Telrakan chapters (two in the southeast, and one in the north).
