[align=center]Well I'd say that an ice elf would have limited control over water... Like, she could be able to breath out a cold 'mist' that, when it touches something, it turns into a kind of thin icy layer. Kind of a more realistic version of ice breath, I guess.
But that mist would be from the water in her body, so I'd say that she'd have to drink a lot of water to use that a lot. Her body temperature would probably be very cold, her skin cool to the touch, etc.
I'd say that if she wanted to make something out of ice she'd need to have a body of water handy first, like a lake. She could have a kind of limited psychic ability over water, so that she can float it up and over to it and shape it into whatever she wants, then freeze it.
She would probably be most powerful in the rain... Like if she could get close enough to you while you were wet, she could just freeze a whole layer of ice over you.
Which is beginning to give me an idea about elemental elves all being different sub-species...
What if I combined fantasy and sci-fi and put every fantasy species on their own planet?
E.g. a planet where elves replace humans, a planet for dwarfs...
The faeries could possibly share a planet with the humans... Since humans are similar to elves in basics, but aren't as magical, not to mention very wasteful, the faeries could be kind of like protectors of the planet...
