Envision a colossal fortress carved from gleaming obsidian, its dark, jagged spires piercing the stormy sky. Surrounding the fortress, swirling mists of ethereal light dance ominously, illuminating runes etched into its surface. Below, a tumultuous sea crashes against the black rock, sending wisps of spray that shimmer like stars. The scene is both haunting and majestic, evoking a sense of ancient power and mystery that captivates the spirit.
