Ancient, mysterious, grandiose cave, intricate stone carvings, Gothic arches, towering ceilings, dimly lit torches, moss-covered walls, stalactites, stalagmites, crystal formations, misty atmosphere, eerie shadows, ancient civilization ruins, abandoned, overgrown with vines, mysterious artifacts scattered around, dusty tomes, forgotten scrolls, dimly lit corridors, ornate stone doors, rusty old lanterns.
