Nixie laughed when one by one all the girls ended up at the bottom of the cavern. She bent over, putting her hands on her knees, trying to regain her breath. "Nice of all of you to join me." She stood up and shook her long hair out of her face. She looked over at the pool of water at Yuki and raised an eyebrow. The Japanese girl must be really trusting to just jump in some strange pool of water. Though, Nixie knew she would have done the same if she had thought about it. The water did look invigorating.. The blue-haired girl walked over to the water's edge and looked down at her. She chuckled, then turned to the other girls when Skye asked what they were going to do now.
She walked over to the cave wall and ran her fingers gently over the crystal rocks, delighted when one of them fell out into her hand. Nixie held it up and squinted her eyes at it. It really did seem to have a soft glow coming from it, but that was really caused by the full moon starting to pass over the volcano opening. She looked up at the tiny bit of moon that was visible and smiled. The moonlight felt really inviting. Everything about this place felt inviting, from the walls, the floor, the crystals and especially the round, crystal clear pool of water.
When she realized she had got distracted and ignored the other girl's questions, she blushed slightly. "Oh sorry. I do have a theory about how we can get out, but bear with me, until I figure out if it will work." She walked over to the pool, set down at the edge, dangling her legs into the water. She shrugged off her backpack and set it aside. "It looks like this pool is connected to the rest of the ocean." She pointed in the clear water. "See that tunnel down at the bottom?" It was at least big enough for two people to swim side by side.
She jumped into the water next to Yuki, smiled at her slightly and then focused on the tunnel.
"I'll go check. I can hold my breath longer than anyone on the island." Since they lived surrounded by water, it had become a standing tradition to have silly water competitions and see who could do various things the best while in the water.
She took a huge breath and started through the clear tunnel. The swim did not take as long as she thought it would. In no time, she was out of the tunnel and in the main ocean. Nixie swam to the surface and took a huge gulp of air. It had taken her a little over 2 minutes, though would have taken longer if she hadn't swam so fast. She looked around her, saw that it was a short swim from where she was to the beach where their boat was docked.

"Good news," Nixie said when she appeared at the pools surface. She looked at the girls and smiled. Her long hair swirled around in the water as she laid back and floated. "This pool is connected to the ocean. If we swim fast, it is about a 2 minute swim from here to the surface." She motioned for the others to join her in the water, grabbed her backpack and secured it to her body.
"Come on everybody; jump in!" She rested her forearms on the edge of the cavern floor and looked around the magical room. Part of her wished that there was a normal way to come and go because she wanted to come back every chance she got. She looked up at the night sky through the volcano's opening, watching as the full moon almost nearly covered it. There was still a slither of moon missing from view. She was still looking up when the rest of the girls jumped into the water and just when she heard the splash of their bodies hit the surface, the moon passed full over the opening.
Nixie's eyes widened as a beam of moonlight shined down on them. It was like the tower of light was some sort of magical barrier. She could not move away from her spot. Subconsciously she reached out and took two of the girl's hands, noticing the everyone else had done the same, until all four of them were holding hands and facing each other.
The water around them began to gurgle and turned a pleasant warm, like a fancy bubble bath. Orbs of water and light floated out of the pool, swirling around their heads and up the column of moonlight and seemed to be following it until it could no longer be seen. A whoosh of air followed the bubbles, caressing their cold, wet skin. The next thing she knew the water around them startled to boil and become hot. It did not hurt, but left a really strange sensation on her exposed skin. Almost a soon as it began, it stopped and the surface got as cold as ice.
Looking up, Nixie noticed the full moon moving away from the opening, the column of light went away and all the strange phenomenon went with it.
"What was that? Is everyone okay?" She looked at the others; they were still holding hands, forming a circle between them.
