The Gladriel Arena or Champion's Arena is a colosseum where all types of fighters of all races compete. The purpose of this arena was to satisfy Adriel, who was bored with his condition on earth. The fights took place all the time until the Grand Tournament which took place every four years. The other tournaments being only playoffs, they were used to select the strongest fighters who could potentially face Adriel himself. Even if he who arrived in front of Adriel was not named "champion", he was considered as such, because victory being impossible against Adriel, it was still a feat to have arrived in front of him. One of the greatest champions is France, which thanks to vampirism could come back to face the angel for over a century.
