Actually, Forest is a half-elf with an unknown past. When he joined The Mohktorians, he wasn't any good at anything. But in an early match against some haflings, he befriended one of the treemen and made this advantage perfect for the team. The Mohktorians won 2-0 and the half-elf got his name, which he accepted with honour.
Later, it was discovered that Forest was a fast runner, when he as a last resort got the ball, he outran the whole orc team. But time was short, and the game was soon ending. Everyone shouted "RUN FOREST", and he really ran and made it!
Yeah, a goal to 3-1!!!
