Cerada (plural Ceradae, pronounced Ser-ah-dah, Ser-ah-dae) are part of an attempt, along with Brachyids, to introduce tool-using semi-sentient creatures into my campaign that are incapable of advanced language and less likely to negotiate than the sentient races. It seems that most campaigns fill this hole with orcs and goblins and such, but I have given these races tribes and nations that remove them from this role.
Ceradae are highly attuned to the earth. Their common varieties are mighty warriors and mighty laborers. Their shaman have powers over the earth itself that they use to protect their tribes from threats.
