Europe, 1911. The veneer of the Belle Epoque crumbles as tensions grow across the continent. New discoveries, strange rumors, and an unshakeable sense of progress culminate to the most fantastic quest of all: the search for the Holy Grail. Enter Otto Lang, a German ex-policeman searching for anything to reinvigorate an adrift life touched with tragedy and disappointment. Otto finds himself thrust into a crossroads of academia, occult intrigue, and outright madness. Surrounded by threats both mundane and paranormal, his impossible search spirals deeper into danger. To succeed, Otto will need to follow the trail wherever it leads. In the end, his survival will depend on his instincts, the caprice of both friends and enemies, and the machinations of providence.
