Brutalist Steampunk, gothic fantasy, moody lighting, rusted metal tones, ash and ember palette. Mech Design: The Oblivion Cathedral Lumbering through cratered hellscapes of a WWI-style trench battlefield, the Oblivion Cathedral is a towering Brutalist Steampunk mech forged in blackened iron and cathedral stone. Standing three stories tall, its body resembles a mobile chapel fused with a dreadnought — thick, riveted armor plates form a monolithic chest engraved with decayed holy sigils and gargoyle vents that spew alchemical steam. Massive pipe-organs on its back howl hymns of war, disorienting enemies with sonic barrages. Its arms: one is a siege-flail wrapped in chains of burning scripture; the other, a baroque cannon belching molten shells inscribed with runes. Spiked treads grind through mud and corpses alike, dragging a spiked censer cart behind it — spreading toxic fog and corrupted incense. A brass cathedral dome helmet crowns its form, beneath which glows a single, cursed eye. Piloted by a bone-armored priest-knight fused to the control throne, the mech is both machine and relic — a walking relic of divine horror. Its presence turns trenches into shrines of ruin. It is not worshiped. It is feared.
