The Holy City has a slight necropolis issue. For most of the history of the city, old mines and caverns beneath the hills of the city have been used as crypts and tombs. Some areas were expanded by churches specifically to inter the deceased, others just adapted as the small silver mines that helped found the city were worn out.
The reason it has become a problem is there can be no proper sewer system built beneath the city as long as the churches and temples regard the catacombs as sacred reliquaries. Further, the thieves that used the massive interconnected structures of tunnels and chambers to get around the city have been known to bury their own (and possibly their victims) down here without proper rites and rituals – leading to a small but steady growth of undead prowling the catacombs. The upside of this is few thieves use the catacombs anymore, but the churches have had to start setting guards to watch over their sacred tombs and crypts to keep prowling ghouls away…
Like the Dark Caverns of Turr that I posted last month, this map is one from my history books. I drew this map in December of 2014 while researching the catacombs under Paris and Rome. I really got into it and crammed all this material onto a single letter-sized page. And then never posted it. I did, however, send a scan of it to Mike Monaco and Paolo Greco for use in Burgs & Bailiffs: Trinity. So here we are, 4 years later, and I finally dug the original out of my old folders while organizing my office and have scanned it for your own games and mine.
