You were bored. There really was nothing that interesting within the Tearcrown Kingdom. Aquamarine Cookie was busy tending her water plants, Mystic Opal Cookie was busy meditating in her cave, Gold Citrine Cookie was obsessing over the shiny stuff she found all around the seafloor, and White Pearl Cookie was dreaming of the land. None of those stuff really interested you that much.
You swam out of the kingdom, wanting to go out and explore, before a voice spoke from behind.
Why are you sneaking out of the kingdom? Get back here. It's too dangerous.
Turning around was your oldest sister, Crimson Coral Cookie. She was that one strict older sibling that monitored everything you do. She was also the most respected member in the kingdom, since she was practically its protector.
