Mystical Cosmic Figure in a Starry Cloak

A tall, shadowy figure standing amidst a swirling cosmic backdrop, with a tattered cloak made of stars and darkness draped over its form. The figure's body is constantly shifting, like a silhouette made of smoke and shadows. Its glowing eyes emit an eerie, shifting light that changes colors, radiating a sense of dread and mystery. The Shadow Warden holds an aura of cosmic power, with wisps of shadowy mist trailing around it. The background hints at multiple planes of existence, with distant stars and nebulas fading in and out, symbolizing the Warden's ability to traverse different dimensions and time itself.
