The Ghostwalk Mantle is a unique and specialised Veil of Darkness used only by Vargard Obryon. Originally commissioned to aid him in his role as the bodyguard of Nemesor Zahndrekh, it was designed by the foremost Cryptek Psychomancer of the Tomb World of Gidrim, the Dagon of the Shadowed Matrix. The Ghostwalk Mantle differs from a standard Veil of Darkness in that it allows Obyron to spirit himself away from the grasps of the enemy even when in combat, thus giving him the ability to redeploy himself and his unit with unparalleled ease, and stand at Zahndrekh's side immediately whenever he is needed to protect his charge.
