The banshee is a harbinger of woe in ancient Eldar legend and mythology, whose cry is said to herald such ill fate that it can even wrench a soul from its Spirit Stone, before casting it into depths of the Immaterium; there to be plaything of Daemons. It is fitting then that the most feared of all the Aspect Warriors, the Howling Banshees, draw inspiration from this unearthly creature and take on its name; and it is from the scream of the creature that is the mythological source of their most potent weapon: The Banshee Mask.
