Raidne Queen of Nightmares

This is my entry to the Rift "Create a Colossus" contest. I chose the water plane for inspiration.
Her name is Raidne and she is the queen of nightmares. She was inspired by Succubus, incubus and mermaid/sirens mythology.
Raidne was once a beautiful young maiden, but was coursed by a very powerful warlock that believed himself to be a god. The awful man punished her because even though she had many lovers, refused to take him as one.
Since then, she lives in the ocean, but at night she likes to visit her victims while they sleep. She seduces them with her music and then appears to them as a very attractive person (either male or female, depending on the victim's sexuality.) and makes love to them. She takes the semen from men and mixes it with her eggs and then plants the egg on an unsuspecting woman, impregnating her. She does this because she can't carry the child (part of her course). After the baby is born, she claims it and takes her to sea with her.
Aside from seducing people she can also freeze them with her music. She often does this before she drags them into the ocean to later eat them or feed them to her children. She can also cause dangerous tides and tsunamis. She rarely engages in hand to hand combat, but when she has to, she can use her long sharp nails and tail to do the job.
