The Gravel Stone Seal is a dark fantasy artifact with a gothic-inspired design, featuring a cylindrical shape with intricate, weathered engravings that depict ancient lightning motifs. Its surface is rough and textured, resembling aged stone, with a muted gray color palette accented by faint, glowing blue runes that pulse with latent energy. The seal is capped with a slightly larger, circular base that has a cracked and worn appearance, suggesting its ancient origins and frequent use in powerful incantations.
