The slow burn of regret and guilt clashes with the grandiose realization that, of the pitiful remaining survivors, he alone bears the mantle of true godhood. Caught between self-aggrandization and heart-searing agony for his hand in the collapse of the world, Artemis spends his precious time tending to his small band of companions and keeping his previous identity mum. 

Though the face he presets is stoic, collected, and a master of executing both plans and people, inside is a turmoil-driven eagerness to compensate for his sins. Those with sharp eyes may catch his crutch of magic - desperate to protect what little niche he's carved out of the remains of the world, no price or risk is too great to preserve his companion's safety.
