Geis

Geis is a mercenary and recurring character in Ys series that first appeared in Ys VI: The Ark of Napishtim alongside his brother Ernst. He later returns in Ys Seven to serve as one of Adol Christin's allies and acts as his rival.

He wields a jet-black poleaxe with frightening skill, manipulates talismans for sorcery and commands alchemically-created fairies inherited from his brother Ernst. He is endlessly critical of Adol and the two of them are often at odds with one another, but ultimately respects his ability and strengths, and reluctantly counts him among his allies.
