Ruler of the Ancient Seas

Serena was the princess of Atlantis, and her tail was gold, which placed her at the top of the order merfolk are ranked in. Her adopted sister Lina and her betrothed Kaelen killed her. She came back to life at an earlier point with everything from before still in her head. She could see what Lina and Kaelen were setting up, since she had walked into it once already. She went down into the Abyss instead. Nereus, the sea god, had been sealed there since old times, and she joined with him. She came away carrying nine divine eggs. The hatching is done in front of the court, and she used the ceremony to lay out what the two of them had done.
