 While the Brethren entertained Thomas Brandon, the executioner (son of Richard Brandon), Morvran slipped away, only to be surprised by a large, pale fish-like monstrosity known as The Pale Rider, who barbarically slew the druid.With Morvran dead and his protective powers no longer in force around the Tower, it was rendered open to angelic interference.On consultation with John Milton, Defoe and Damned realised that The Pale Rider was himself an angel, a seraph of the first sphere, who had come to prevent Terra Moto revealing the secrets of the angels.
