There were a lot of things about night creatures that no one knew. Especially their pack mentality. They were supposed to be wild mutated beasts who did not care about anything. However, that was far from the truth. For some strange reason, some of the species between the night creatures cared about each other enough to live in packs.
No one knew the reason behind this as most of the time night creatures followed a strict hierarchy in which those at the lower rung were constantly killed by the creatures above them. But for some strange reason, everything the werewolves knew about the night creatures became void once they were inside a 'dungeon'.
Unlike in the wild, the night creatures rarely if ever, fought amongst themselves. Instead, they behaved like a collective mind and did their best to exterminate the intruders. This was the reason why the beasts found inside a dungeon were much more dangerous than those found in the wild.
