A menacing assembly of dark skeletons, each figure a macabre silhouette against a shadowy backdrop. These skeletal beings, their bones blackened as if charred, stand in a grim formation. The scene is steeped in a monochrome palette, where the subtlest hints of color arise only from the cold gleam in their eye sockets. The air is thick with an aura of malevolence, as the skeletons exude an eerie, otherworldly presence in this dark, haunting tableau.
