Crasti
this Priapulin word, which translated loosely into Basic as "food kin", was used to describe small, immature crast. The crast and the Priapulin existed in a unique relationship, in which egg-bearing crast were consumed by the Priapulin, but the eggs were actually nurtured in the digestive juices of the Priapulin's stomach. When the eggs hatched, the Priapulin regurgitated the young crast.
