From publisher blurb:
This primer gives game masters a new option for encounters and campaign antagonists! Meet the Noctrex! Insectoid-Draconic creatures with a strong affinity for shadows and the undead, Noctrex were created by a more mysterious entity for one purpose...transformation.
While their mysterious masters would occupy the denizens of a world with macabre conspiracies and eventual undead armies...the Noctrex would be secreted into the world and safely hidden in caves which they could hunt from. As the Noctrex hunt and grow their numbers, they begin to bring with them a strange chemical gas that terraforms the planet for their undead masters!
This item details the Noctrex and the strange ecology that they create via their existence. Pick it up today for some ideas for interesting encounters!
