So it would be one of those town invasions from Teostra we read about in the lore. Say, were such things already in other Monster Hunter games or would this make MH 4U unique in that regard? (I'm pretty sure though this kind of thing is already in MHFO with Rukudiora and Rebidiora as well as Teostra and Kushala Daora.)
