Corrupted hearthlings that spawn like any wildlife, very aggressive and have some randomized stats and randomized equipment (with randomized gildings) which can be looted upon defeating them. They wander around like dryads, but sometimes can start doing some "human" actions like chopping trees, setting up a fire, fishing, sleeping on the ground, gathering fruits and berries. If the random equipment roll made them have weapons - they are as aggresive as snakes/scorpions. If not, then they are as aggressive as badgers. Corpse decays into something similar as player corpse, and can be buried in a dolmen which with each corpse buried accumulates dark power that can be used in rituals to get temporary buffs but inflict permanent wounds that can be healed only with alchemy or roots.
If they are to defeat the player, they loot 1-5 random equipment slots from KO'd player, and have a chance to finish off & murder as boars.
