Water. Earth. Fire. Air.
Long ago, the four nations lived together in harmony. Then everything changed when the Fire Crewmates attacked.
Only the Impostor, master of all four elements, could stop them. But when the world needed him most, he got ejected.
A hundred games passed and my brother and I discovered the new Impostor, an airbender named Lemon, and although his airbending skills are great, he still has a lot to learn before he's ready to save anyone.
