The native species of the death world Burnscour, grendelspawn are fierce predators that make effective, if dangerous, guardians or trackers. Relentless hunters, they possess keen senses, razor-sharp teeth and claws, and the ability to spit acid. Two types of grendelspawn, hunters and queens, are currently catalogued in the Imperial Lexicanum. In time, further research may yield other subspecies of grendelspawn. Grendelspawn hunters, the most common kind, are vaguely reptilian quadrupeds the size of a human. They constantly salivate through their bared fangs. Grendelspawn queens are as large as an elephant. They have tentacles in addition to claws and teeth, but their bulk makes them much slower than the hunters.   Grendelspawn queens are always female. It is unknown how impregnation is accomplished; they do, however give birth to dozens of sexless hunters that grow to full maturity in six months. The sexless hunters instinctively protect the queen and, by extension, anything else around the queen’s location. They can be trained as easily as dogs can, but no amount of training will override their imperative to protect the queen. Grendelspawn hiss and growl but seem to have no language of their own.
