A lair is where monsters of a certain type spawn aroundspawns [[animal]]s and other creatures. It takes 21 strength to destroy. Animals do not spawn exactly on randomly around the lair tile but nearby up to within 50 (100?) tiles away. They Animals can leave the area as they move around and also be lured awayby a player. The name on the lair object shows you what type of creature will spawn around that location.
