Ruby Palace

«Ruby Palace» (紅玉宮) is a red palace that has magnificent spires on top. It is the 100th Floor of Aincrad, and also the last Floor. If the game had proceeded as it was planned, this would have been the place where the clearers who had reached this floor alive would have fought against the final boss, Heathcliff, and, if they had won, they would have finished the game.

Trivia

 * In Sword Art Online: Infinity Moment, Kirito gets to fight the last boss, Heathcliff, on this floor.
