As the creatures approach, a couple of things become quickly apparent.
One. The are not human, or of any common humanoid race. They are hunched and feral looking, with short black fur over pinkish skin. Big ears, big teeth, big jaws. And they don't have much knowledge of personal hygiene, it seems. They wear bits of filthy leather and cloth, barely enough to let you know they are probably not just animals, although you might prefer they were. They aren't carrying weapons other than claws and teeth, but those look serious.
Two. They are not stopping to talk. They charge straight towards Daladain and Kealoha. Being more of a "Sneak Attack" fan than a front line type, Kealoha goes back up the stairs, position herself to either keep running if they follow, or drop behind them them if they pass by. They are headed right towards Daladain and Qui and they look mad.
Three. That noise they make... the constant hooting, laughing, shrieking,
gibbering... it's very unnerving. In fact, at the supernatural level.
As they rush in, everyone must make a Will save (DC 10) or be "Shaken".
Perhaps the one positive thing is the geography: the narrow doors of the ship and the confines of the stairwell slow them down and force them into a line as they approach.
