Princeps Seniores On the field of battle, each maniple is commanded by a Princeps Seniores - a Princeps who has proven themselves beyond reproach, and worthy of such a vaunted position.
After assembling their battlegroup, the player should pick one Titan in their maniple to be commanded by their Princeps Seniores - note this on the roster.
Personal Traits Each Princeps Seniores has a Personal trait, which is in effect for as long as they are on the battlefield. Immediately before deploying their force, each player should roll a D6 on the table to the right to see what their trait is. If both players agree then they can each pick a Personal Trait instead of rolling a D6.
