In Umbral, the young thief Rascal breaks into the royal palace using a rare eclipse as cover for the theft of a priceless gem. During the heist, Rascal witnesses the death of the King and Queen, the first step in the invasion of the world by the Umbral, mythical shadow creatures... and no one knows it's happening. Umbral is the latest collaboration between the creative team of Antony Johnston and Mitten, who co-created the post-apocalyptic and impressively expansive series Wasteland.
