When the Bastard City fell to Kyros' armies, Tunon the Adjudicator - Archon of Justice - claimed the palace for his own. Now, Tunon's Court serves as the center of law and governance for the Tiers.
Points of interest
The area is centered around the terrace from which Tunon delivers his judgement. Below it lies the platform, suspended over the pit where those judged unworthy are thrown in. When you first visit, delegations from the Disfavored and the Scarlet Chorus are present, pleading their case.
