[@Force and Fury] You are making a mistake by approaching this from a scientific perspective in the first place. [url=http://i3.kym-cdn.com/entries/icons/original/000/018/816/its-magic-i-aint-gotta-explain-shit2.jpg]It's magic[/url], you can't explain it with physics. Just tell me what your gift does and don't bother explaining the natural processes behind it because that's pointless in this setting. You say you want to show the water is all around us as compared to fire, but characters can have gifts allowing them to make either out of nowhere. 

Also, I am not sure where you get that "water" characters are limited to being the support for "fire" types, or to being "calm and life giving". The most powerful and aggressive NPCs you will meet in this RP have affinity for water.
