Vitae et Mortem
The Underworld is a fighting pit beneath Rome. It is open to all. There is no holds barred gladiatorial combat. Often gladiators are not quite human either supernatural themselves or with a supernatural sponsor. It is populated mostly by criminals and vampires. Mortals often witness things that they should not but know not to say anything. Those that don’t understand this principle don’t last long. It represents the ultimate in bloody gladiatorial combat for those that desire more than the surface can offer. As such high stakes gambling often takes place there.
