Undines/ondines are “a category of elemental beings associated with water, first named in the alchemical writings of Paracelsus.” They cover a variety of water-based creatures, including mermaids.
They are generally known as being water nymphs who often live in waterfalls and tend to resemble humans, but lack a human soul. Sound familiar?
Furthermore, because undines lack human souls, they are mortal. If they find true love, however, they can shorten their lives in the mortal world to gain an eternal immortal life. In other words…
…undines become undying through the power of love.
