Assembly

The Assembly is a building located in the center of Praxus on Cybertron. While the city itself already is a mesmerizing experience of the finest Cybertronian culture has to offer, the Assembly is the undisputed main act. The building houses facilities for classes, discussions, presentations, demonstrations, as well as a theater, concert halls, holographic entertainment rooms, musea, lecture halls, libraries and archives; all that the citizens from Praxus could need in support of their pursuit of science, technology, art, philosophy, and culture. The building itself is a domed structure, with moving sidewalks, leading past pieces of art, to carry guests to and from the building.

The Assembly was where scientists from Crystal City and Nova Cronum presented their findings. It was destroyed during Megatron's attack.
