Nod's bloodsport venue, located in the Redlight District. Organized combat between willing participants, between participants and beasts, and between participants whose willingness is a matter of contractual interpretation. The Coliseum operates under its own local customs, and the savvy ownership sells subscription viewing to fights broadcast on the Wire, making it one of the network's few reliable revenue sources. The fighters who survive long enough to develop a reputation can earn substantial income. The crowd is mixed-species and enthusiastic. The Mercenaries Guild recruits from the Coliseum's survivors. The Slavers Guild supplies some of its combatants. E. Who operates it?
