Bayroad (베이로드, Bae’ee’rohdeu) is the name of a secretive pit said to be hidden somewhere in the Tower. In this pit special fighters, collectively referred to as "Mad Dogs", are pitted against each other in brutal deathmatches. A characteristic of Bayroad is the long and straight appearance of its arena. Mad Dogs run out onto the arena from both sides and fight until one drops dead. It is said that even if one tries to escape, a terrible bed of blades waits at the end. Because the shape of this arena resembles a road, it was named Bayroad, "the road where Mad Dogs bark".
