Gale, the First Frost [Champion Concept]

Hey guys,

Thought that the freljord needed someone to sort out this civil war mess, and i started fishing up an idea for a subzero esque swordsman named Gale (irish name meaning 'stranger') who was captured, tortured and manipulated by . Lissandra uses some frost magic ish to bring forth the Frostguard to determine a ruler of the Freljord and is successful, however the soul of the eternal watcher is absorbed into Gale. He rejects Liss with his newfound power and escapes. Right now i have a facial design and its looking pretty cool, what i wanted to ask you guys about was costuming and backstory to see if we can build this champion from initial design up. I really think he could end up awesome.
