There will be water. Let it cleanse you and do not let go.

They had left the buildings behind, they had moved through a forest, there was a clearing, a hill and, at long last, a waterfall. Hoseok slid smoothly into the water, careful to keep his body on the surface, not wanting Ten to drown. He swam toward the waterfall and moved through it, his pearl lighting up and the water seeming to glow as well.

It actually had cleansing properties, healing as well, at least just then. As sacred as he was. He felt that Ten could use some healing, inside and out. Finally they made it through the water and into a cavern. It was still damp at first, but then less so. The walls had crystals growing out of them, many of them glowing, shining their light on their surroundings. Hoseok had always thought it was beautiful, even before he'd taken residence. It was a long, winded way, but he moved fast and he hurried. Ten would have time to marvel later, when he'd be better able to appreciate it.
