The walls look organic. And those blue things...
...I think they're polyps of some kind. They live inside the wall and are part of the structure. National Geographic would go nuts over stuff like this.
It's a drawing of a man -- a human -- sticking a strange, polyp-shaped object into his mouth... Ugh...
In the next drawing, he seems to be able to breathe under water. Convenient. If somewhat radical.
It's a drawing of a man cutting his finger open and squeezing some blood into a bowl together with some green, mossy stuff. Then he mashes it together, and...oh, gross...
...he dips a black pearl in it and eats it. That's barbaric. Maybe the stories about the cannibal mermen were true after all.
But, hey, in the next one he seems capable of speaking fluently with the creatures that brought me here. I wouldn't mind that, if it could get me the hell outta here.
This whole structure looks organic, and there are polyps living inside the walls.
It's a drawing of a man sticking a polyp down his throat so that he'll be able to breathe water.
It's a drawing of a man mixing some green, mossy stuff with his own blood, applying the mixture to a black pearl, and then eating the pearl. Afterwards, he's able to speak with the mermen.
I'm cold and wet, and I wish I could just click my heels together three times and be home.
I'm cold and wet.
If this gets infected, and I have to chew off my finger to fight the gangrene, I'm suing somebody.
Ouch!
The things I do to save the world. Worlds.
I've always had trouble swallowing pills. Especially huge, golden, magical ones.
Well, here goes nothing.
(swallows)
Oh, this is so digusting...but I have to get outta here.
There's fresh oxygen coming through here.
These polyps must process the oxygen in the water somehow. That's how I'm able to breathe in here.
There's water out there. Lots of water. I'll just drown if I try to leave.
No, I'll just drown.
