Image: Game asset concept sheet, two variants of the same

Generated from: Game asset concept sheet, two variants of the same object side by side on a plain dark grey background, orthographic three-quarter view, painterly dark fantasy, cold grey carved stone and blackened iron with celtic knotwork. The object is a RUNE COLLAR: a heavy ring-shaped clamp about one metre across that fits around a thick tree root lying on the ground. LEFT variant "BRIDGE": the collar is closed and smooth, a low stone lintel arching over the root, with an engraved channel running across its top face, unlit. RIGHT variant "TAP": the same collar with its iron jaws driven down and biting into the root, splitting the bark, with pale cyan light welling up out of the bite and running into the channel. Both objects isolated, no ground plane, no text, no characters, even lighting so the shapes read clearly.
