A giant fortress can be found just off the Hydlaa Plaza through an old and long tunnel known as the Old Quarry Road. There can be found many people from all over Yliakum who come to the Arena to train their skills. It houses many savage creatures such as Trepors and Tefusangs. Mercenaries and the more ferocious gladiators can be found, some employed by the Arena, some there of their own volition and bloodlust. It is a dangerous place that is for not the weak-hearted. Merchants can also be found within the walls, selling a variety of items.
