Valerius is a gaunt man with parchment-thin skin that seems to stretch over his sharp, prominent cheekbones. His hair is a thin, snowy white wisp that escapes from under a velvet skullcap. He is constantly shrouded in oversized, moth-eaten noble robes that trail behind him. His eyes are his most striking feature, a piercing and vibrant violet that dart about with terrifying intensity, noticing every minute detail of his environment while his body remains fragile and slow.

He speaks with the haughty cadence of a man who still expects a footman to open his doors, though he hasn't owned a door in twenty years. Valerius is obsessively intellectual, often ignoring basic physical needs like food or sleep to calculate the precise geometry of a ley line. He treats everyone as an equal student, which usually results in him lecturing peasants on the molecular density of their mud with genuine, though detached, kindness.

Valerius is the last surviving member of House Aethelred, a family once renowned for their contributions to magical theory before their estates were seized by the crown for unpaid debts and perceived madness. While his siblings fled to find manual labor or petty merchant roles, Valerius stayed in the ancestral library until the literal roof collapsed. He realized that modern spellcasting was stagnant and efficient, lacking the raw power his ancestors once commanded through pure mathematical focus. Over decades of poverty, he refined standard spells, stripping away the safety nets meant for weaker minds to create his enhanced variations. His body has withered under the strain of these experimental castings and a life of academic seclusion. He now wanders the world, a forgotten lord of a non-existent land, carrying the singular dream of founding an academy where magic is practiced as a precision science rather than a convenient tool. He believes that the universe is a puzzle that only he has the patience to solve.
