The aura surrounding a knight, he realised, was fundamentally distinct from the arcane energy wielded by wizards. Where arcane energy depended heavily on an innate, almost fated talent—born from the mystical fabric of the world—knightly aura was a discipline of the mind, forged and refined through sheer willpower, focus, and rigorous training.
A theory among the learnt wizards held that arcane energy was a gift, bound to the ancient forces of the cosmos, gifted to a select few. Wizards could harness this energy only if they possessed a natural affinity for it, as it thrived on a resonance with one's soul—a bond that could be nurtured but not created from nothing.
Aura, on the other hand, was thought to be a reflection of the individual's spirit and could be cultivated by anyone willing to train their mind to the utmost.
