The Hintertombs.
Unlike the tomb-labyrinths proper, the Hintertombs were less like the resting places of the revered and more a bunch of dug-out holes into which the corpses of everyone else were dumped. "Unceremonious catacombs filled with graves and death," Balyn had once read them described as, probably in some scrawled tomb prospector's journal in Byrgenwerth.
"Though to be completely accurate, there's also poison. A lot of poison. I'm not sure if it's naturally occurring and keeps seeping through the walls, or if it's because all of the bodies down there just rot away into toxic sludge, but either way it's definitely a third point that needs to be mentioned."
"You sound like you are having difficulties, good hunter."
Balyn sighed, then sat down with a thump at the feet of the Doll and leaned back against the nearest gravestone. It might have been seen as disrespectful, but from how the Doll had explained it the graves were in memory of past Hunters who'd visited the Dream, and Balyn figured they of all people would understand.
"Yeah, it's tough. Poison everywhere, exploding oil jugs, and then some screaming madman tried to bury a sickle in my head. But you know, that's not the worst part."
The Doll had been brought to life specifically to be a caretaker, to look after the well-being of hunters in the Dream and, perhaps some day in the future, after something more. Even so, it took several seconds before that fundamental nature overcame her caution.
"And what, then, is the worst part?"
Balyn, unaware of her inner struggle gave a deep sigh, the kind that conjured images of decadent poets weeping over bloodstained roses and opium-laced wine. A sign of the pervasive sense of ennui that assailed an elegant soul bewildered by the bestial crudities of the world.
"It's so boring!" he wailed.
Okay, maybe not that elegant.
"Exploding oul urns and murderous madmen?"
"Well, no, but honestly all of Yharnam is like that. I can get impaled by a madman on any street corner in the city."
"And have," the Doll noted, conceding the point, even though it felt to Balyn more like she'd scored one.
"Then you get it. When I was exploring the Pthumerian labyrinths, or Loran, or Isz, it felt like I was doing something meaningful, looking into the secrets of ancient lost civilizations, maybe trying to make some sense of what's happening in Yharnam now. But the Hintertombs...they're just a hole dug out of the earth. There's no secrets there to be found, no ancient treasures or lore of the Great Ones, and as for the combat...look, you know how there's usually a pretty tough enemy guarding each layer of the labyrinth for the Watchers, right?"
She nodded. The Doll did, in fact, remember everything that Balyn had said to her. Possibly as some kind of penance for unknown sins.
"I do."
"Well, I even fought one of those down there, and let me tell you, even that was a real boar!"
