Their footsteps echo throughout the stairway as they descend, first surrounded by stone, but then the stone gives way to a smooth cylinder of jewel. Perhaps crystal, diamond or a pale emerald/sapphire, it's difficult to tell, but judging by the size - large enough to contain them and the staircase - it would be worth more than most kingdoms could afford. Indeed, it may even be worth more than an actual kingdom, including every piece of property within!<br/><br/>Beyond, there is a slightly distorted image of the water and its inhabitants. Mostly, there are brightly coloured fish, and the occasional small shark, snatching one up to feast on. An octopus moves about, a few eels as well, and sea serpents gaze through the glass curiously, noticing the moving creatures on the other side. A gigantic manta ray also floats by. It looks simply incredible.<br/><br/>Finally, they arrive at the bottom, in a sort of dome made of the crystal, and three corridors branch out, one back towards the castle, and two others, close but branching out each at a 45 degree angle.
