Beneath the land of Britain, a great army is sleeping. On a visit to an old church, Daniel Tully and Freya Reynolds awaken two ancient knights from a centuries-old slumber. They are kidnapped and taken to an undergound city that stands in peril, beseiged in all directions by a vicious warhost. Nidergeard is the only thing protecting the upper world's blissful ignorance of mythical forces that have been held at bay since the creation of the world. In order to return home, Daniel and Freya must strike at the heart of the opposer's power.
