Amalthea, the stone is positively ancient. The mortar dried centuries upon centuries ago, and everything is now covered in a profusion of dust, cobwebs, and ivy. The stone of the statues is brittle and worn away; somehow the statues have eroded faster than the walls around them. At the same time, everything here seems frozen in time, not at all like it's been exposed to constant rain and cold for centuries. The whole thing creates an eerie dissonance like a splinter of ice in Amalthea's mind, and the blank stone eyes watching her don't help.

I noticed that you should probably get a better bonus for dwarven Stonecunning. From what I remember it's double your proficiency, which is enough to get more information on this.
Taniwha, you can't see any traps that lie on either side of the gate. No murder holes, no pit traps, no swinging scythe blades. There could always be some magical trap you can't detect—after all, what opened those gates?—but another clue leads you to believe that the way is safe. You see well-worn ruts in the mud, as if from carriages passing through frequently. You think back to Drina's cart and realize that the make of these carts must be the same if not similar.
