A dark fantasy sigil with a glowing red eye, black horns, fiery runes, and smoky shadows.

Shape: A circle of dark metal with fiery, lava-like cracks along the edges. The edge appears to glow from within, with small sparks occasionally shooting out. Central motif: A large, red obsidian eye in the center. The iris glows faintly orange and the pupil is vertical, like a reptile or demon. The eye appears to follow the viewer from any angle. Horns: Three black horns curve out from the circle – one upward and two obliquely to the sides. They are cracked with glowing red veins and slope inward, as if protecting the eye. Runes: Along the outer edge of the circle are carved angular runes, glowing deep red. They appear to move faintly, pulsating like a heartbeat. Shadows: Thin, smoky shadows hover around the entire sigil, as if darkness is leaking from it. Sometimes the shadows take on vaguely demonic forms—horns, hands, or gaping mouths—but only for brief moments before dissolving again. The shadows always seem to move toward the eye, as if drawn to its power. Color Palette: Deep black, blood red, glowing orange, and subtle violet hues in the living shadows. Effect: When the sigil is displayed in low light, the eye appears to blink slowly, and the shadows extend toward anyone who looks too long—as a warning. See more
