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. Therefore, many of them try to spend every klik they can spare at the Assembly. The building itself is a domed structure, with moving sidewalks, leading past pieces of art, to carry guests to and from the building.

The Transformers Trilogy
About 8.7 million years ago at the start of the Great War, the Decepticons attacked Praxus with the intention of making it one of their greatest victories over the Autobots. In the chaos that ensued, they had the Assembly implode.

In 2002, Bluestreak was made to relive Praxus's, and the Assembly's, final day.
