The plot of The Luciferians takes place in Tyrol, a mountainous region between Austria and Italy, which was the scene of numerous macabre rituals in the underground of medieval castles, between the 13th and 14th centuries, a time of notable events in the history of the humanity. 

This time, the victims are the young couple Raymond and Eliza, whose ties, from a very early age, were united by an important commitment.

The outcome of this enigmatic story and the fate of Eliza and Raymond can be found in the second volume, The Templars, which describes in detail historical facts about this important order of medieval knights.
