The Strength of the Few (Hierarchy Series, Book 2)

The Strength of the Few is the second book in the Hierarchy Series. The story picks up from the events in The Will of the Many. Vis is in Obiteum and is with Caeror (Ulciscor’s brother). Caeror explains to Vis that there is an enemy called the Concurrence. Many years ago, to prevent the Concurrence from enslaving everyone, there was a war. To combat the Concurrence, the world was split into three near-identical copies i.e. Res, Obiteum and Luceum. There is something called synchronism, which only Ka i.e. the Concurrence has been able to achieve, meaning he is able to exist in all three worlds at the same time. The only other person to achieve this is Vis.

A lot of the story follows Vis (or versions of Vis if you like) in Obiteum (where Caeror is), in Res (where the Academy is), and in Luceum (where he meets a man named Cian).
