<https://s.mj.run/HceeswzJRh0> A dark and foreboding sigil burned into the wrist of a red-skinned tiefling’s arm, glowing with pulsating black and crimson energy. The intricate design features jagged lines and curling tendrils, forming a chaotic, swirling pattern that appears alive. The rich crimson hue of the tiefling’s skin contrasts sharply with the eerie glow of the sigil, while cracks and faint scorch marks radiate outward from the mark, as though the infernal power is spreading through the flesh. Shadowy wisps of smoke curl upward from the sigil, creating an ominous, supernatural aura. The background is a dark, ethereal void, faintly illuminated by the pulsing glow of the mark, with spectral whispers and shadowy tendrils barely visible in the distance. The scene exudes menace, arcane power, and the sinister weight of betrayal. --s 750
