A towering, ornate grandfather clock made from dark, polished wood, standing in an ancient, mystical hall. The clock's face is intricately carved with arcane symbols glowing in faint blue light, with runes spiraling around the golden clock hands. The pendulum is an eerie, floating skull, suspended by glowing magical chains, swinging back and forth with an ethereal hum. Around the base of the clock, twisted vines with glowing, otherworldly flowers wrap around its legs, and the entire clock pulses with ancient magical energy. The scene is set under a stormy, night sky, with lightning flashing, casting dramatic shadows on the clock, making it look like a relic of immense power
