Feron Herm (Patreon)

Feron Herms take care of the broodmothers inside a feron hive. While the full female and male ferons usually become warriors, herm ferons make sure the broodmothers are constantly pregnant with new grubs. 

Inside the abdomen, feron herms carry infectious worms they can inject into victims. The victim turns into a grub in minutes and develops even more worms to carry in their breasts. After a few years, the new grubs skin starts to herden and their gender defines their place in the hive as they become a herm, a broodmother, or a warrior feron
