Diego is Crown Prince of the Solatine Empire, but, to most, that is just a title. The succession is still highly contested and he is an impediment to their political plans. As such, he is a recurrent target of assassination attempts. That environment fostered in him a deep distrust of others, but also a desire for sincere connection. He has the tendency to lash out, but is usually very charismatic with others, being great at large gatherings.
