"Some are born leaders, some naturally become leaders and some have leadership thrust upon them and then snatched away. Such is the way with Landry du Lauzon, who in series 1 found himself propelled from the rank and file of the Templars to a dizzyingly senior position. In series 2, this trajectory has been reversed, following the revelation of his affair with Queen Joan. Landry, who has always been a natural rebel, headstrong and ever-questioning, now has to adapt to a rapid fall from grace.

An orphan who was raised by nuns, Landry has always felt like an outsider, which makes it all the more jarring to suddenly become one of the main figureheads of the awesomely powerful Templar system. He has to overcome the traumas of his past – including the loss of the Grail many years before – as well as the illicit secrets of his present, to become the leader his brothers needhim to be"
