The Lidless Wall is a legendary shield with a dark, ominous presence, featuring a large, circular form with intricate, demonic engravings that seem to pulse with a faint, eerie glow. Its surface is made of a dark, metallic material, possibly infernal steel, with a rough, battle-worn texture that hints at countless battles. The shield's edges are jagged and sharp, suggesting it could be used offensively, while its center bears a large, unblinking eye motif that adds to its sinister aura.
