Montero isn’t a particularly imposing man, but is utterly inscrutable. He hides his thoughts and emotions behind his mask of severity.
He dresses in immaculate suits and is well groomed.
As the man in charge of the Princes affairs, Montero is all business. He is currently the only man who is allowed access to his whereabouts and his needs.
He runs a tight ship and doesn’t tolerate disorder.
In the Prince’s years of absence, he has kept things running. He sees to it that the status quo is not upset.
