The creatures also developed four long mandibles, which were used to drag prey into their large mouths. To make full work of their mandibles, they would attack by lunging or biting, using their huge bulk to force prey into a corner, where it can be trapped and devoured.
Aureillans used these creatures to attack and kill. after releasing hundreds of them they let them go and not caring weither or not they all died. They only attack at night and weren't good for sneak attacks.
