"Formicans" is the Achaean term for ant beastfolk. These ant-men reside in all parts of the world, building vast underground empires in enormous tunnel networks that often bring them into conflict with other subterranean races, like dwarves and dark elves.
Formicans have a typical beastman appearance, at least by way of insectoid or arachnian beastmen. They have the heads, legs, and abdomens of ants, but they have a pair of human arms with three-fingered, thumbed hands and a smaller pair of arms on their midsections. They have human-like mouths that allow them to speak and eat like men, but they still have large pincers. A wide variety of formicans exist, and their appearances vary, but in general they have these similar attributes.
The matriarchal society of formicans operates on a strict caste system, in which exile or execution is the punishment for disobedience to the Queen. The Queen, however, is not the only one who breeds. Certain females become her Handmaidens, who are allowed to bear children with the select males of her harem, ensuring only the finest children. Those females deemed unfit to breed become Soldiers or Workers, while males deemed unfit may simply become food. Formicans produce fungus farms and breed giant docile insects for food. Their intelligence and the might of their empires are not to be underestimated. The greatest Empire of Formicans is believed to dwell in the Endless Wastes.
