Tenzin nodded to her question and gestured with a wing to the nearest tunnel beside them, Tunnel O. "Oh yes, there are many. Down this way is the Core, also known as Polaris. In there is the river I warned you about—which is a long flow of rushing water. It feeds into the waterfall," he said, glancing up at the falling water fondly. "It is dangerous to fall that far, though, so I would strongly advise you not to ride its waterway all the way to the waterfall." He gestured then toward the second-nearest tunnel, Tunnel H. "Down that way are a few other caves, and at the end there," he paused to motion toward the far edge of Pisces to Tunnel M, "is a long but cold tunnel. Through that you can reach a room above us that is a large expanse of water, though it is warm water."

Tenzin looked down at her and nodded gently. "Oh yes, there are others that you may not be able to visit at first, but as you become efficient at breathing the water in the air you will be able to travel greater distances." He pointed with the tip of his wing, curled in toward himself, to both himself and Lamia. "You can create ice pockets around your gills," he decided to suggest, not wanting her to feel completely strung to the water as if it were her fate. "Perhaps trapping water there, and freezing ice around it—and when you run out, you may summon water, but all these things you will learn. With time," he said with a smile.
