The Trigdale Metallurgy company constructed the Trigdale refinery on Seregar for the purpose of refining tolium. The refinery's operations ceased when the mining syndicate withdrew their support from the world, leading to its abandonment.
The refinery presented itself as an enormous and intricate network of chambers, passages, conduits, and elevated walkways. Although the corporate red of Trigdale was still visible on some surfaces, the majority of the exterior exhibited rust and discoloration, with climbing plants and vegetation covering significant portions.
