The Debate Chamber, also known as the Voryle Debate Chamber, was a state-owned structure located in Capital Borough on Voryle that was used by the Governing Council of Voryle to debate a variety of topics concerning the governing of the city and the planet. While in session, the Debate Chamber was sealed and could not be entered by anyone, regardless of the reason. In 27 ATC, the Governing Council of Voryle met in the Debate Chamber at the behest of Prime Minister Namos D'callo to discuss his motion that Voryle join the Sith Empire, ostensibly to receive aid against a colossal Sher Kar that was rampaging across the city.
As any action affecting planetary neutrality required a unanimous vote, D'callo – with the help of Sith Lord Sera Artofen – intended to kill his opposition using urnsor'is poison, pumped in via the ventilation system. Isla Ahnkett became aware of this plan and located the urnsor'is, killing it using Force lightning. Samantha D'callo, Namos D'callo's daughter and Ahnkett's ally, forcibly entered the Debate Chamber at this time and confronted her father, revealing his plan to his peers before chasing him out of the chamber.
When the Governing Council was disbanded and Voryle became a monarchy, the Debate Chamber no longer saw use, though it was preserved on Queen D'callo's orders.
