The hatch opens without much effort, and the light from it transports him into the dungeon. When Llwn enters, he can see that behind some of the translucent walls is water, like behind the glass in an aquarium, only said water is empty. Or, mostly empty, in the depths of the water, far out of view of any normal person, Llwn can notice a large red serpent curled up, it's gaze locked on him, unwavering, there is one of these on the other side of him as well.
The path ahead is illuminated by torchlight, and visibly leads to a large chamber, in the middle of which is a single table with a piece of paper on it.
