First, The Shells

Ages ago, on a dismal world of swamp, I led the Army of the Light to a demon-infested manaforge obscured by vines and fog. My soldiers left that world in a haze of flame and smoke, the scent of burning mana and victory in the air. We will do now as we did then. We'll begin by collecting the empty canisters they use to hold and transport fuel. The ethereals, and especially their automatons, will have them.
