Geras' Hourglass is a mystical time-manipulating artifact, featuring a symmetrical, geometric design with a sleek, metallic frame that encases translucent, glowing sand within. The hourglass stands on a sturdy, ornate base with intricate engravings that depict ancient symbols of time. The sand inside emits a soft, luminous glow, shifting between hues of gold and blue, symbolizing the flow of time. The glass chambers are smooth and polished, contrasting with the slightly weathered metal frame that shows signs of age and use.
