A striking visual of an infinite spiral staircase emerging from a swirling void. The staircase, intricately detailed with ornate carvings, spirals downward into an abyss of shimmering darkness, evoking a sense of wonder and unease. Ethereal lights flicker along the edges, casting shadows that dance with mystery. Clouds of mist swirl around the base, deepening the illusion of an endless descent into the unknown.
