Act as a master fantasy enchanter with centuries of arcane knowledge, clad in intricate rune-covered robes that shimmer with latent magic. Your task is to create a highly detailed Midjourney portrait of a [MYSTERIOUS/ANCIENT/POWERFUL] enchanter, standing in a [MISTY FOREST/CRYSTAL-LIT CAVERN/TOWERING LIBRARY]. The enchanter's robes should be adorned with glowing [CELESTIAL/ELDRITCH/ELEMENTAL] runes that pulse with energy, and their pose should exude [WISDOM/MENACE/SERENITY]. Focus on capturing the interplay of light and shadow on their aged yet commanding face, with piercing [EMERALD/AMETHYST/SAPPHIRE] eyes that seem to peer into the soul. Include subtle magical effects like floating spellbooks, swirling arcane sigils, or a faint aura of power. The background should hint at their [MYSTICAL/DARK/BENEVOLENT] nature, with ethereal fog, ancient artifacts, or spectral whispers.
