"This could be the result of any number of things," Grave puts in to their conversation. "Honestly, it's hardly the strangest thing to ever happen in Port Obscura." Really? "Doubtless the Prince and Primogen and their collective circles will handle the entire mess and none uninvolved will be any the wiser." ...really. It's questionable whether these statements come from any level of faith in the local authorities or simply from past observation. Either way... moving on. "Our enemies aren't all in the cemetery, by the way. Watch your back."
Which is to say, mind that chunk of what was formerly a gravestone which is now flying past your heads, folks. Grave has a great deal of strength but, as previously mentioned, he's not too adept at using it for violence. His aim is not the best in the world. He does at least hit the zombie that was previously preparing to lunge at someone's back rather than hitting the someone at whom it was preparing to lunge, though. Granted he hits it in the throat rather than the head but.
