What was willpower?
There were a lot of official definitions of this term, but few of them described the concept that matched his current understanding of this term.
Willpower was intent. Willpower stood for the willingness to endure hardships. Willpower kept warriors aloft in battle.
To Ves, willpower took on even more meaning after personally witnessing expert candidates and expert pilots in battle. Even without seeing them in action, those with strong will such as Venerable Brutus and Venerable Jannzi already distorted the reality around them with their latent will alone!
Yet what these amazing individuals accomplished was not purely a product of willpower. Expert pilots only emerged after they unconsciously developed their spiritual power by merging it with their strong wills.
