You swim along, now noticing that the creatures are getting bigger. You are stopped dead when you see a hippocampus just ahead of you, her bright pink shaming the other colors below her. She looks over at you, blinking as if to make sure she's not dreaming.
You swim over to her, wondering what she's doing in the reef. You introduce yourself, but before you can finish she begins to speak.
"I know you're a wanderor, you're all the talk of the reef," she says. "I am Iseawyn, and I was just swimming back to the ocean over the reef. Good excercise you know?"
"How did news of me travel so far up the reef already?" you ask.
She looks at you, a bit confused. "Well, this reef curves in one big circle. At least this upper layer does, anyway. You went up to the very tip, and are now swimming back to the ocean, where the sign is."
She smiles when she sees how confused you are. "Don't worry about it, within a few more minutes you'll be back to where you started, and you won't have to take my word for it." She winks at you and swims off.
