Aetherium Engine

The Aetherium Engine is a powerful Precursor construct created during the Sixth Era. Designed as a weapon of mass destruction, the Aetherium Engine was supposedly employed by the Precursor Empire during the final years of their role. 
Co-created by Artificial Precursors Azaria and Nuhll and is the only collaboration between the two. Nuhll wanted to create a weapon for the Empire he so dutifully served. Azaria created the Engine to ensure that there would be no more wars, as it would serve as the ultimate deterrant. Although he soon realised that the Precursor Triumphirate had other intentions for the Engine, and began to regret his part in the creation of the Engine.
