The Abyss

Beneath the whole Arena, including the plains of Sorrow, is the Abyss. There is nothing worse than this place, even death seems generous when you are sent here. If you lose a duel or battle the arena gives way and you fall down, down, down to eternity and back. Once you land you are thousands of Miles away from the surface. Your magic doesn't work and light has forsaken you. The cruel and sadistic ruler of this place, Diablos, will make your life a living Hell here, some even say the Abyss is Hell.
