The foundation of the Templar finances is examined and clearly laid out. This is necessary in order to understand what finally happens to them.

Frontier lays the basis for the fall of the Holy Land and the effects it had on the Templars. Reinforced and secure, they lose their ground to the Mamluks. The power struggle plays out, the Holy Land is finally lost to the Crusaders, and the Templars move back into Europe to find they are financially secure, but have no reason now for existence

The final installment, Legend, examines the fall of the Templars. Their financial holdings appealed to a failing monarchy, they become the target for the financially strapped French King, and are arrested, tortured, tried and burned.
