TheMountaineer also known as Icy, was a normal human...until..we'll get to that later...

Her father died at a very young age during a war (Later found out to be the soda war)...not many details. She was around ten at this time... And no one really knows about her mother or what happened to her. For six years Icy had to fend for herself until... taking up and abode in the mountains, far away from civilization.

When she was around sixteen she was sick of living alone, was adopted by a guy named (The latter became her adopted father) illager (A very important Illager) who at this time had two other children... GracieMockingjay his daughter and a son content_inc

Also well she was there she met LegendarySi who turned out to be her older brother, who had been separated with her shortly two years before her father died and mother vanished. No one knows what happened to separate them....and why it took around six years before this all happened....

That remains to be a mystery yet untold.
