Olivier was a Sanbrequois prince from birth, as his father Sylvestre was Emperor. Anabella sought to involve Olivier in affairs of state from a very young age, though he expressed boredom with such matters. She expressed great physical affection towards the boy, and Olivier was often seen resting his head in his mother's lap as she stroked his hair, even as she sat on her throne and carried out official duties. He was always idly playing with a wooden toy soldier.
