Calypso was once a human several hundred years ago, they can barely recall who they were at this point in time. But they know they lived in a small village by the sea, they know they grew up on ships and riggings, they know they spent their entire memorable life sailing. They think they were drowning, Calypso would say if asked about the moment she was transformed, she remembers a storm and being thrown from the ship, plunging through freezing cold water and sinking to the bottom with no hope of saving themself even if they did manage to get back above the water. They don't quite remember the esk that transformed them, that saved them, but Calypso hardly minds, they've met so many other esks that've taught them throughout their existence that they don't mind who actually changed them at this point in her existence.

Since becoming an esk Calypso has journeyed across the vast reaches of the ocean, from shore to shore and visited each island they found on their way, seeing the full scope of the world from the ocean shore and at rare times venturing far enough to lose the crashing of waves and the caress of salt on the wind, but never for long. She's visited and discussed the world both with those older than herself and those young enough to still be learning their footing in their new skins.

She took on the name Calypso when she heard learned the tales of Greek gods and their dogma from an esk that had been raised amongst it, garbing herself in the name as it resonated deep within themself. The other had looked at them oddly, reminding them of the crime Calypso had committed in the stories but they'd taken the name regardless, it felt correct and it was hers now. Her actions would not match that of the goddess' from legend but she would carry the name with pride regardless.
