Dark Mark Serpent Sigil

Description

A coiled serpent threads through a grinning skull with neon-yellow eyes, rendered in black and grey with a toxic green aura. The imagery echoes the Dark Mark from Harry Potter—the emblem of Voldemort’s Death Eaters—symbolizing allegiance, power, and the lure of dark magic, as well as memento mori themes. Vertical composition suits the calf, with bold outlines, stippled texture, and selective color accents that heighten drama and readability from a distance.
