Monarch: a secret society dedicated to protecting humanity from the supernatural. Recruited from the army and pressed into service, new Monarch agent Riley White must navigate a strange new world full of magic and monsters. On his first day on the job, Riley learns that an ancient evil long thought dead is about to return and usher in the end times. A master vampire from the long forgotten past has resurfaced in London, and it's up to Riley and his partner, agent Jay, to stop him before it's too late.
