Vidalshal, also called Bidashal, operates as a high-ranking Elf aligned with King Joseph de Gallia, maintaining a partnership of mutual benefit rather than servitude. His mastery of Elven magic eclipses even the strongest human square-class mages, enabling feats like neutralizing assaults—such as Tabitha’s spells—with mere thought. Under Joseph’s directive, he crafts Firestones, enchanted artifacts whose explosive yield rivals small atomic bombs, designed to devastate Romalia.

As Luctiana’s uncle, he governs an isolated Elven oasis within their desert domain while spearheading clandestine human research. This includes authorizing Luctiana to abduct Tiffania and Saito for analysis, though he later orchestrates their escape, blending pragmatism with unpredictable ethics.

During a critical fourth-season confrontation, he interposes himself to shield Henrietta and her fleet from an Ancient Dragon’s lethal firestorm, prioritizing immediate peril over his alliance with Joseph’s grander machinations. His motives remain opaque, executed with clinical detachment, obscuring whether his actions serve hidden agendas or mere professional obligation.

Physically, he embodies Elven nobility: hips-length blonde hair, piercing blue eyes, and pronounced pointed ears. Tied to his desert heritage, he holds titles like "Bidashal of Nephthys" and "Lord Bidashal," overseeing both his community’s welfare and arcane studies. His narrative arc weaves loyalty to Joseph’s destructive aims with inscrutable personal inquiries into human nature and magical extremes, cementing his role as a calculating, enigmatic force.
