Arkthar, the chaos necromancer, looms ominously, engulfed in an aura of fear and confusion that spreads like tendrils of malevolence. His presence is monumental, towering in a hyper-realistic spectacle reminiscent of a Yugioh monster. Intricate details define his dark robes and skeletal features, each element meticulously crafted to enhance his nightmarish allure. Shadows dance around him, swirling in a vortex of chaos, as his eyes glow with an unholy light, summoning despair to all who dare gaze upon him. His staff crackles with forbidden magic, pulsating with power as he prepares to unleash his malevolent wrath upon the world.
