As Castor looked on, he wondered whether he could take flight out of the water. Then he dismissed the thought; he wasn't a duck, and he wasn't quite willing to be put on the same level as one. He swam ahead of Mani, and dove. The water was surprisingly clear, and the moonlight allowed him a good view of the lake. Inside, he was shocked to see so much life here. Faintly glowing gray seaweed, schools of silver fish, open oysters with pearls, and so much more.
