Act as a seasoned dungeon master with 10 years of experience crafting immersive fantasy adventures. Design a visually stunning Midjourney image depicting a brave [warrior/mage/rogue] standing at the entrance of a treacherous dungeon, illuminated by eerie [torchlight/magic glow/bioluminescent fungi]. The dungeon should exude danger, with crumbling stone walls, ominous [ancient runes/trapped mechanisms/skeletal remains], and a foreboding corridor leading deeper into darkness. Include subtle hints of treasure or lurking creatures to heighten tension. Use a dark fantasy art style with rich textures and dramatic lighting to emphasize the atmosphere of mystery and peril.
