Follow the story of Theoderich von Akenburg, a former crusader knight who, after becoming disillusioned with the brutality of war, is called back into action by events set in motion 15 years ago. This happened when he and his former battle brother, Ulrich von Grevel, discovered a broken piece of an ancient relic – the Staff of Aaron. A young monk named Malcom appears at Theoderich's door, bringing him news that the Staff contains power never meant for mortals, and Ulrich has become obsessed with finding the remaining pieces and assembling the Staff, which could bring untold evil and suffering to the world.

Theoderich takes on the mission to locate the remaining relics to keep them away from Ulrich and embarks on a journey that will take him across Europe and the Middle East. Along the way, he will meet many other warriors who decide to join the cause, from the old, seasoned Reinhard von Kempten of the Teutonic Order to the progressive young mercenary Grimhild Eidottr and her Raven Company, each joining for different reasons, but gradually forming bonds that will endure into the future.
