High Council Pavilions

Housing the Autobot High Council and the Council of Ancients, the High Council Pavilions were the center of government on Cybertron.

Dreamwave Generation One continuity
The High Council Pavilions were the main center of government in Iacon before and during the Great War. After Optimus Prime became leader of the Autobots, a Decepticon assassination squad managed to breach the Pavilions security and nearly succeeded in killing Prime. Later, the High Council Pavilions became the Autobots main base when Shockwave launched an attack on Iacon. When Starscream activated the planetary mechaforming substructure, the High Council Pavilions were destroyed along with most of Iacon.

After Optimus Prime and Megatron's disappearance caused the Autobots and the Decepticons to fracture, the ruins of the High Council Pavilions served as the base of the Protectobots. Despite the ongoing Border Wars, the Autobots or Neutrals found time and resources to rebuild the High Council Pavilions. Starscream had some of it destroyed and the rest followed suit during the next 2.5 million years.

Once the Great Shutdown came to an end, Iacon was rebuilt again in an Autobot-Decepticon team effort. The High Council Pavilions were also rebuilt.
