What do you mean "finally taking up his role as Page of Breath"? What does that entail?

A Page of Breath is a natural leader. A Page creates or provides others with their aspect (the latter in this instance) and Breath can be inferred as meaning Direction. So a Page of Breath provides people with Direction. Allowing him to lead an army to a specific goal very easily. Pages also take a long time to actually embrace their role and this Tavros (or (Tavros) as he’ll probably be refereed) has had a lot of character development and time to work towards his role.
