Brief History:  Una was born int the Northern water tribe she loved to look at the water benders bend the water and ice, she soon learned how to bend water at age 5. her mom taught her everything she knew until Una was 10. On Una's 10th birthday she met and saved Lakota, her pet polar bear.  The she went to a water bending class and she soon excelled in water bending and joined an Advance class when she was 14. When she turned 16 she decided that she wanted to help find the Avatar and find out who her father was, So she packed up she things and left the Northern Water tribe and headed for the  Vermilion Dragon Empire.
On her way to the empire she traveled through the Earth kingdom and the Northern Air temples, and they taught her about the history of bending and how to understand the spirits and the Avatar. They also taught her helpful techniques for her bending.  When Una arrived at the  Vermilion Dragon Empire she started looking for a teacher to help her master water bending, she learned about blood bending and acid bending. Even though Una has not learned these techniques she is anxious to learn them.  
Char planer: Una masters water bending in a year on her 18th birthday and starts to learn blood bending. She experiences two great pains, the first must be a physical pain, the second is great emotional pain.  She learns light bending, masters light bending learns illusion bending, masters illusion bending.

Hi It's good so far, I like it. Just a few things though, the Warriors of the Elements are similar to the Avatar in the sense that they are BORN being who they are, even if they don't know about it at first. Perhaps, would it be okay to edit that out?

Approved. Just note that the future part of your history, for when she turns 18, learning Light and Illusion bending, and mastering them, are gonna take a long time :p but they can be done.
