I just saw a video of (people) ashes being added to volcanic rock to be used as coral reefs jumpstarts basically, gave me an idea I’m too lazy to write so in case you wanna use it, the two people your thinking of. One of their ashes got transferred to a part of the sea before the area was deemed unusable. BUT they’re a ghost, now all alone in the middle of an ocean bored out of their mind when DUH DA DUH here comes your other character a MERMAID. Yes I am cringe. Ghost x mermaid :3
