The Gladiator Pits can be found below the Arena in Betancuria West. It is home to the gladiators as well as some of the creatures they do battle with. The Princess enters the pits during the Uncover the Dhorn Spies quest.
Spoiler: The Princess can gain access to the area through Sharita Senneset, a madam who frequently provides the gladiators with women, or by breaking in through the main floor. |
