Vogg is going to get sick today, because he's going to wander out to find Godric's body and do some proper viking stuff. It's a thing. He'll probably come back around talking nonsense, and probably half of that nonsense will be in his native tongue so like... no one will understand him.
Hestia also knows where Moody lives, so she can help with the evacuation. She'll also be kicking some monster ass when she can.
Colin can help scout the area for other safe places? Because you know, I cant imagine that they entire town is going to fit in Moody's house. It's going to be full enough with the sick/injured.
Lilu is going to do whatever she needs to do to protect Polaris. Katie is also kind of useless, so she'll be doing... something useful, but not engaging in fight.
Ava is probably going to perch herself up somewhere and shoot arrows at the monsters eye sockets, but like before she'll bow out when it gets too dangerous.
Charlie is still pretty injured-ish, and wandless, but he'll take something blunt incase he needs to fight something along the way.
