Slight necro (no pun intended), but I have a related problem.
Over four hundred visitors' corpses (at least 200 of which were warriors, judging by the number of weapons I picked up afterwards) have been hastily pulled underground into vaults in a system of tunnels, out of sight of the arcane.
(Yeah, those were visiting mercenaries, poets, scholars, consorts, performers, etc. Apparently they didn't get the memo that a nasty necromancer siege had been ongoing for two years. It's a humanitarian disaster, made worse by the necessity of first neglect, then haste in burial.)
I have no desire to make a
raven bomb (spoiler alert!)
I've made over 400 caskets, and a new multi-level warren of graves to hold them. Two hundred of these caskets have been placed into their cubbyholes, and all have been set to burial (Y), citizens (N), pets (N). None are tombs. And none are being used to bury the visitors. Unless I missed something in those three settings, I'm under the impression that all 100 of my dwarves should be (probably weeping while they're) hauling the skeletons from the vaults to their places of rest.
None of the visitors reached my tavern, except for a few who I saved via the aforementioned tunnel network. Almost all of those died when they wanted to leave (I bunched them up both so they would have a better chance and so that they could take out some zombies on their way. Only one escaped, in the end.) Not even those who broke bread or drank with my dwarves are being buried.
Any ideas on how to inter these remains? And don't say magma. I've already dug the catacombs and prepared their furnishings, so there had better darn well be a way to use them. At this point, I would convert it all into a formal corpse vault before abandoning it, but as stated, I'd like to inter them properly.
