Biography

Io served the Kingdom of Arago as a knight, with the stated aim of protecting the happiness of its people. The king's self-righteous conduct wore that down until he left the country entirely, and he has supported himself as a mercenary in Dagsion since. He inherited his horse, Rocinan, from his late father, and the animal is treated in his profile as the one thing he carried out of his old life.

Personality

He is described as an ambitious young man with high standards. His listed likes are chivalry, self-discipline and Rocinan; his interests are caring for the horse and staying quiet. The last of those is listed as a preference rather than a manner, which fits a character who walked out of a knighthood rather than argue about it.

Personal Skill

Skill	Effect
Mounted Push	Activates when he uses his mobility to strike first, raising his hit rate

Mounted Push is learned at level 20. It rewards initiating combat while in a cavalry class; his personal ability, With My Steed, adds Shield +3 and Dodge +30 under the same condition. See Skills for how personal abilities sit alongside class and weapon skills.

Role in Battle

Io fights alongside Rocinan and is built around mobility, closing distance to strike before the enemy does. A pre-release screenshot shows him in the Cataphract class.

Recruitment

Io can be recruited in Part I on all four paths for a gold fee. His requirements are lowest on Dietrich's path, where he is a natural pick by Chapter 5 to round out a team of six.

Path	Support level	Renown	Other requirement
Cai's path	3	10	4000 gold
Dietrich's path	2	3	800 gold
Theodora's path	3	10	4000 gold
Leda's path	1	6	1500 gold
