The Sentinels just like a moonlight and a tide

Huā followed Andromaque, letting the other girl lead the way into deeper water. She had swum alone plenty since her northward travels had begun, but she had missed this- swimming with company. It had been a long time since she'd seen her sisters.

She shivered just slightly as the cold temperature of the water seeped into her bones, but she wasn't bothered enough to climb out. She remained in the water, occasionally touching her soft paws to the rocky floor, before lifting them up to doggy paddle again. She felt something intriguing, and grasped it in her paw, best she could. She lifted a paw out of the water to see, and- it was a tiny pale conch shell. Not particularly special or above ordinary in any way, but Huā's eyes lit up at the sight of what was treasure to her all the same. She glanced at Andromaque, wondering what she would think.
