Ignacio is a powerfully built man of regal Hispanic bearing with salt and pepper grey and black hair worn in a tight ponytail tied with blue and silver ribbon. He wears the deep blue and silver heraldry of his house, featuring a blue dragon around a sword. He has a carefully maintained beard and striking green serpentine eyes.

Ignacio is a brave but domineering man who projects the stern authority of a military veteran. He is a habitual gambler who hides deep-seated cowardice and guilt behind a mask of noble pride.

Ignacio was once the pride of the Spanish imperial army, a banner man of House Martinez whose courage was legendary. During a horrific siege, he witnessed a creature so terrible it broke his spirit. He stood paralyzed as the royal guard and the king's son were slaughtered. Only he remained, saved by a desperate plea to a dark power that answered in the shadows. He bargained his soul to never freeze in fear again, resulting in his reptilian green eyes. After the massacre, he turned to drink and dice to drown his shame. He raised Miguel, his wife's illegitimate son, as an act of penance while shielding the boy from the truth of his lineage and Ignacio's own fall from grace. Now he travels as a mercenary noble, gambling with coins and souls alike to keep his secret.
