"Well, nu, it's either the catacombs under the city or, feh, the marshes past the outskirts," Anzu says, with a shrug.

"The catacombs are more convenient, I suppose? I believe the water table's not so much a concern as, nu, the lack of soil past a certain depth. Makes a feld easy to avoid, should one need to, too. Makes my job rather harder on occasion, but it'd be hard regardless, and mercifully, I rarely have to deal with those what can't pass on because they were buried not in the proper manner."
