The princess leads us through the passage until we reach the very end, where a tall glass wall separates us from a tank of water on the other side. It's not terribly large, but gives its inhabitant enough room to swim around. Or, if they prefer, coral stairs to lead up to the dry part of the encasement where a small section of limestone ground remains. Solid bars of the same material weave together, forming a different type of wall.
Perio floats backwards, hands behind his head as we approach. He does a double take as he sees Ariana, immediately swimming up to the glass and pressing his hands against it. Refusing to return the gesture, she moves up the matching steps to meet him on the dry ground. He immediately joins her, flying to the gray limestone ground and pressing himself against the bars.
"Ariana, my love. You have come to free me."
She inhales. "No, Perio."
