Khione

"Hot? You dare insult me? I'm cold, Leo Valdez, Very Cold."

- Khione

Khione is the Greek goddess of snow, sister of Zethes and Calais, and daughter of Boreas, god of the north winds. She is depicted as a goddess in the series, although in mythology she is sometimes mistaken for a nymph.

History
Khione is the daughter of Boreas, the North Wind and Oreithyia, whom he abducted. The Eumolpidae in charge of the Eleusinian mysteries claimed descent from her, as the mother of Eumolpus with Poseidon.

The Lost Hero
When Jason, Piper, and Leo visit Boreas's penthouse suite in Quebec, they are greeted by Khione and her two immortal demigod brothers Zethes and Calais. As soon as he sees her, Leo develops an instant crush on her, but she doesn't like him because she can sense the fire within him. She makes him wait with Calais while she and Zethes take Jason and Piper to see Boreas. She supports the idea of turning them into ice statues, but her father disagrees and she is extremely angry at him but is forced to listen, resulting in her letting them go.

Later, when the demigods are flying over Detroit, she summons a strong wind to knock Festus out of the sky and freezes the wires in his head to damage the control disk, thus preventing him from flying. Leo is confused about the frozen wires but, doesn't suspect it was Khione.

When the trio visit Aeolus, their godly parents convince him to help them, but before he does, Khione whispers in his ear, tells him that Gaia is waking and that he must kill the demigods, but Mellie, his assistant, helps to save them and get them to California.

Finally, Khione appears at the Wolf House, revealing her connection to all the problems the demigods faced on their quest, and orders the monsters to kill them. Leo uses fire to fight her, knocks her down, and tries to hit her with a flaming hammer, but she turns into snow and melts. It is unknown whether she is actually gone or just retreated into the snow.

Powers and Abilities

 * Possesses the standard powers of a goddess
 * Can turn humans or demigods into ice. Anyone who goes near the ice statue will possibly be frozen as well, hinted at the end of The Lost Hero.
 * Can make icy wind blow something out of the air.
 * Can turn herself into anything associated with snow.
 * It is also possible that she can fly or levitate herself with wind, like Jason, since her father is a wind god and one of her spheres of control is icy winter winds.
 * She also has the ability to create something similar to a nuclear blast, only instead of heat it is made of cold.
 * She can also speak fluent French, although this is because her father is based in Quebec.
 * She can also summon very violent blizzards and other snow-associated calamities with a wave of her hand.
 * She can also do something similar to charmspeak by whispering in people's ears. She can do this because, as stated at the Wolf House, her voice is 'like snow, soft, and very cold.' She convinced Zeus to close Olympus and convinced Hera to sneak out and come to the Wolf House. When she does this, she says that she is only confirming peoples' greatest fears.
 * Since a god's Divine Form is able to melt snow, it is unknown whether she has one.

Appearance
Khione is is very beautiful and proud-looking. Her skin is unnaturally white and pale, like snow. She has lush black hair and cold coffee brown eyes. She wears a white silk dress.

Trivia

 * In some ways, Khione is the second series' equivalent to Luke Castellan, since she (somewhat) helped them in the beginning, but in the end she ambushed them and tried to kill them, along with the fact that she especially hates her father, Boreas, similar to how Luke hated Hermes. Because of this, it's possible that she will, like Luke, help the demigods defeat Gaia in the end, although this is only a theory.
 * She hates mortals for two reasons: One was because they never honored her, even in ancient times, and the other reason was because many mortals believe in the concept of global warming and she thinks that the concept is ridiculous.
 * Even though it hardly ever snowed in Greece, they still had a snow goddess, albeit mentioned in passing. Interestingly, Rick Riordan always asumed that there wasn't a goddess of snow because of where Greece was until sometime before making The Lost Hero. This is probably why she didn't get a cabin at Camp Half-Blood at the end of The Last Olympian, although it is assumed that she doesn't have demigod children anyway.
 * She's insulted when she's called "hot" because she's the goddess of snow.
 * It could be implied that Khione was attracted to Jason because when she saw Jason and Piper holding hands, she burned their hands with cold. Lycaon said that Jason also made an impression on "her" referring to Khione, but that could be because Jason shocked Khione really badly.
