[h3]Halls of the Old Lords, beyond the Old Labyrinth (depth 4, floor 1)[/h3]
And so the four Hunters assembled in front of the Nightmare Headstone to venture through the marker reading “Halls of the Old Lords”, and soon found themselves awakening in a place that seemed somewhat reminiscent of the tunnel where they had awakened before going to face Arrayah. But though architecturally similar in isolation, they soon found that the area they were now invading was quite different than that, opening up into a smaller room populated by creatures that were undeniably horrifying, but nothing next to the abomination they had just slain. They were faced with several [url=https://bloodborne.wiki.fextralife.com/file/Bloodborne/Pthumerian_Undead_Concept_Art.jpg?v=1501106861476]undead Pthumerians[/url] shambling about, accompanied by a handful of [url=https://bloodborne.wiki.fextralife.com/file/Bloodborne/Nightmare_Apostles_Group.jpg?v=1501240748499]obscenely huge spiders[/url]. But thoroughly blooded as they now were the Hunters slaughtered all of them almost effortlessly and without so much as receiving a single injury.
At one point during the fight, however, one of the undead Pthumerians was staggered when Torquil – aided by the Deception Rune – sneaked up behind it and delivered a mighty blow with his axe. He felt his instincts responding to its helplessness and moved in to finish it off, but did not perform the usual visceral attack  he had intended and expected. Instead he found himself rooted in place next to his victim while he felt something in his head shift, and the rest of the party would bear witness to the amorphous mass at the back of his head abruptly bursting out into a thick, long slimy tentacle. This new limb struck swiftly, burying its tip in the top of the Phtumerian's skull, only for it to contract and ripple as though sucking something out of the creature's brain. Its job done the tentacle promptly retreated back into Torquil's head, leaving him disoriented and unnerved.

Setting that event aside, the Hunters managed to scrounge up four blood vials before moving on. There were two different doors to go through, but since they had Gerlinde with them to show the way they took the shortest route toward their destination. Here they faced another crowd of undead Pthumerians, only now with a couple of them armed with guns and shooting at the Hunters from afar until dealt with. Things looked to be rather dangerous for Gerlinde at one point, but thanks to the aid of Ophelia and Farren they managed to get through with only some minor scrapes.
The party managed to find another three blood vials before moving on to the next room, where they fought more giant spiders as well as two [url=https://bloodborne.wiki.fextralife.com/file/Bloodborne/Snatcher_Power_Up.png?v=1499362620753]very big and powerful Pthumerians[/url]. Despite facing more powerful opponents the Hunters once again managed to get through unscathed; Torquil even managed to trip and fall at one point, ending up prone and defenseless, but was saved by the fact that enemies kept missing him due to the Deception Rune. Despite the hardships they went through there, all they managed to find there was a single quicksilver bullet.
Finally they found themselves in an elongated hall and facing a single opponent who immediately stood out as significantly more dangerous than anything they had fought there so far: an armored eight-eyed warrior in strange garb, wielding a flaming sword and fearsome fiery magic. This ended up by far the toughest fight during the trek, but was still nothing compared to the likes of Arrayah or even Paarl. Even though they worked well together, the others had to save Torquil several times, as this wicked swordsman seemed impervious to the effects of his Deception Rune. Torquil ended up grievously wounded before they managed to slay their opponent, but managed to inject himself with a blood vial to save himself before he lost consciousness.
They managed to retrieve another blood gem from the remains of the floor guardian, only to proceed to the other end of the room where they found an elevator.
In total, Farren benefited immensely from applying the Heir Rune to himself and gained 1400 blood echoes during the journey, whereas Ophelia, Torquil and Gerlinde acquired 700 each. It took them a total of twenty minutes.

“My first time through here I just ran past all the guards,” Gerlinde told the others as they rode the elevator down. “It goes deeper, but we don't need to go there to reach the basin. It's also more dangerous the deeper we go...  This is my first time back here, and I haven't been any further in than this. Or... well, I went to the next room and got killed, and decided it wasn't worth running all the way back here.”

[h3]The Waters of Reflection, Halls of the Old Lords, beyond the Old Labyrinth (depth 4, floor 2)[/h3]
As the elevator arrived at the bottom of the shaft, the Hunters would disembark and arrive in a room that was mercifully vacant of all the horrors that usually lived in these dark, forgotten spaces. It was a fairly big, square room – twenty by twenty meters and looked to be nearly ten meters tall – with just two doorways opposite each other, one open that they entered through, one closed. Spread out in the four corners of the room were four two-by-two meter square basins, though none of them appeared to contain any water. Two of them appeared simply empty, one to be partially filled with rubble that had fallen from the ceiling, and one appeared half-full of glowing molten lava.
The most notable thing in the room, however, was a circular basin in the precise center of the space. Bathed in bluish sconcelight reflected by huge mirrors mounted under the ceiling in the corners of the room, this basin – with a diameter of about three meters – was full of water. But despite the fact that the surface of the water appeared perfectly still, as though it itself was a mirror, the light seemed to constantly be shifting, swirling and flickering within its depths.

“There it is,” Gerlinde announced happily, pointing to the central basin. “That's the one! Just stand over it and look at your own reflection. If you imagine anything different, the reflection will change to match it. And when you're happy with what you've imagined, just jump in the water and that'll be the new you!”
