Colloseum Diabolus
Mhaldor's arena, the Colloseum Diabolus, was the last arena to be created, due to the fact that Mhaldor was the last city to be built upon the continent of Sapience. Its construction was delayed after a particularly bad Landmarking year as punishment to the city by Lord Sartan. However, upon its completion, it proved to be the most interesting of the arenas.
It is comprised of four areas. These areas are all connected by a series of mirrors. One must stand at a mirror, (each area contains one of these mirrors,) and say the correct word to move to a specific area. The words can be discovered by reading any of the mirrors.
