I guess I'm going to pitch in with my CS. Been a while since I participated in a roleplay like this. Time to warm up my keyboard.
Name: Nevea (Derived from the Italian for Snow, Neve)
Age: 17
Godly Parent (Greek or Roman): Khione, goddess of snow and ice.
Magical Power (If any): Nevea has the ability to control cold itself, lowering the temperature or even solidifying it. She can also freeze and coalesce water vapour to use as shards that she can send at opponents. However, this ability can tire her if used with too large of a scale.
Weapon: Putting this after Magical Power because it makes much more sense that way. She prefers to use whips of pure, solidified cold, formed using her power. She also occasionally uses a sword formed out of Stygian Ice. Its fragility is reversed and intactness sustained by her power passively flowing into the sword.
Appearance:
Personality: Nevea is, before anything, narcissist. Very. At first glance you might think she's a daughter of Aphrodite, but not at all. Second of all, she's controlling. Everything she does, she uses to move up in the metaphorical ranks. Despite her controlling nature, she's very sneaky about it. Unless you know her very well, you wouldn't be able to tell that she's only doing things for her best interest. She talks silkily, weaving tales and ideas through her words with cold finesse, to keep you from knowing that she's using you until she's thrown you away like a toy. There really isn't a need to say that she's mean.
Other: Skills: She moves like a snake, with finesse, and stealthily. Her whips are like an extension of her body, and she uses them as such. Her movements flow into each other with quick, silent grace.
