Image: Game environment concept art for a top-down action

Generated from: Game environment concept art for a top-down action-adventure. STRICT CAMERA: orthographic projection, camera pitched 33.7 degrees above horizontal, no perspective convergence, no vanishing point, 16:9. The whole room is visible at once; the camera never moves. SUBJECT: "Cistern of Echoes" — an underground Norse-fantasy stone cistern hall, 21 x 16 metres, the water-distribution room of a buried vault. Layout that must be preserved exactly: a raised entry landing under a tall round-arched gate in the NORTH wall at top-centre; a large circular runic inlay carved into the floor at the centre; four rectangular sunken water basins, two upper-left and upper-right, two lower-left and lower-right, filled with dark still water; a deeper sunken sump pit across the bottom-centre; in the pit's far retaining wall a blind arcade of four small round arches; low doorways in the far LEFT and far RIGHT walls, each glowing with warm firelight; a low parapet running across the very bottom of the frame. CONCEPT A — ARCHITECTURAL. Make built mass the landmark instead of light. Raise a monumental stone distribution head on the room's centre line: the four-arch arcade grows out of the pit wall into a real freestanding structure of piers, voussoirs and a heavy cornice, standing above the floor with the runic inlay as its footing. Add a colonnade of squat buttressed piers along the left and right walls, a shallow gallery ledge over the north landing, and stepped stone kerbs around every basin. Controlled asymmetry: the left-hand basins have visibly subsided and their kerbs are cracked and tilted; the right-hand side is intact. MATERIALS: cold grey-blue dressed limestone, 25 cm courses, wet and stained, mineral crusting at old waterlines. LIGHT: cool cyan from the water and the runic inlay, warm orange counter-light from iron braziers on the parapet and beside the north gate. Deep shadow between. Volumetric haze low over the water.
