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

Generated from: Top-down three-quarter view of a Norse vault chamber, painterly dark fantasy game concept art, cold grey ashlar stone with carved celtic knotwork bands. A colossal dead tree-root has burst through the UPPER RIGHT corner wall and sprawls across the floor. Tall walls on the far and both side edges (about 7 metres, reaching well above the top of the picture so no outside is visible over them); the NEAR edge at the bottom is only a LOW PARAPET about 0.85 m high with a flat coping stone, so the floor behind it is fully visible. A wide arched doorway with a portcullis of iron bars sits in the near parapet at bottom centre, with steps descending away. On the left wall an arched entry bay with three steps down into the room. A large carved circular seal rosette is inlaid flat in the floor left of centre. Three flat circular rune couplers lie in the floor at the lower right, linked by thin engraved channels. The ONLY light sources are: pale cyan light glowing out of the engraved channels, the rosette and the root's cracks, and one small warm amber lantern flame near the left entry bay. Everything else falls into deep blue-black shadow. Strong contrast, no ambient haze, no text, no characters.
