Image: Top-down three-quarter view of a Norse vault ciste

Generated from: Top-down three-quarter view of a Norse vault cistern chamber, painterly dark fantasy game concept art, cold grey ashlar stone with carved celtic knotwork bands. The room is a rectangular hall with TALL walls on the far side and both sides; the NEAR edge at the bottom is only a LOW PARAPET with a flat coping stone, with a plain gap in it at bottom centre where steps lead away. A dry stone WALKWAY runs all the way round the edge of the room at floor level. The middle of the room is a SUNKEN BASIN filled with still dark water, about knee deep, its surface reflecting firelight. Four short stone ramps lead down into the basin at the middle of each side. Standing in the water, LEFT of centre, is a small round stone ISLAND rising just above the waterline, and on it a heavy collapsed slab of vaulting covering an iron drain grate. In the far wall a deep alcove with a small stone plinth holding a single squat wooden powder keg bound in iron, glowing faintly. On the left wall a tall arched doorway with steps. Four iron braziers burn on the dry walkway with warm amber flame, their light rippling across the black water; everything else is deep blue shadow. No text, no characters, no UI.
