A pivotal scene in my story involves a supernatural dragon-demon thing showing up at a church service attended by 300-odd people and slaughtering them all to a man. As is so often the case in writing, I've worked out the big details of this event but I've stumbled on the smaller ones -- namely, how is such an event cleaned up? This is actually somewhat plot relevant since a follow-up scene I'd like to include involves the Church (who are the ruling authority in this universe) laying out the bodies of all those killed in the attack so their families and loved ones can claim them. I wasn't sure if this could be done though, since 1) I don't know how much time organizing something like this would take and 2) given the nature of how they were killed, many of the bodies are going to be in bad shape. So, given this, what's the likeliest way the aftermath of an event like this would be handled? How long would cleaning the site realistically take given the setting (a fantasy expy of 18-19th century Paris)? Would bodies be presented for families to take even if they're mangled, and if not, what would be done with them?
