The High Board Room, situated within Otoh Gungan, functioned as a hydrostatic bubble-chamber. It was from this chamber that the Gungan High Council governed the city. During the Invasion of Naboo, Qui-Gon Jinn and Obi-Wan Kenobi, two Jedi, were brought to the High Board Room to account for their arrival in Otoh Gunga. Despite the Jedi's predicament to save Queen Amidala from the Trade Federation, Nass declined to offer assistance; however, Jinn employed a Jedi mind trick to obtain a transport to Theed. Furthermore, he orchestrated the liberation of Jar Jar Binks, who was imprisoned in the Board Room and facing harsh consequences for violating his exile.
The debut of the High Tower Board Room occurred in 1999, coinciding with the premiere of Star Wars: Episode I The Phantom Menace.
