Undine

A spirit who resides in a cave under “Undine’s Spring”, out of view of the rest of the world. A long time ago it seems as though she appeared before humans, but now she’s a shut-in.

Hating the humans who pollute the waters of the world, she mercilessly preys on any who dare enter her terrain. Absorbing them into her body, she assimilates their body to become one with hers.

Though she dislikes humans, she seems to hold regrets that humans and monsters aren’t existing in peace as they did in the past. A close friend of the Queen Slime, Erubetie, they treat each other as equals. They also seem not to interfere with each other’s dealings.
