The Arena is a building in the Guild which is used for safely teaching Warrior Skills and where magicians can have a formal battle. The Arena is made up of eight spires that curve up to meet in a point. The base is a sunken stone circle covered with white sand and the spires space evenly around it. From the spires base, stones steps rise to the level of the garden. On one side is a square portal that allows access inside via a short underground staircase.
The Books all neglect to mention How this is the only building with Directed Energy engineering (it creates a shield) without resorting to the Black magic process of magic stone creation. But continue to remark on what a big change the chamber of ultimate punishment and magic gem technology are.
