The day after Vicente arrived in Grandis, he began organizing what would be needed to prepare for Nina's stay.
She was still training to control her newly awakened powers when Vicente went after the teachers behind the Seidel Magic College.
Vicente was very direct with the professors of that institution, offering them resources in exchange for helping the family protect and observe Nina.
Vicente's point in these conversations wasn't to get undue favors for Nina but to get a prior understanding from these teachers about who she was and some of the family's needs.
Once that was settled, Vicente went to the royal palace to see King Seidel again.

"I heard that your sister was successful in awakening her powers. How is she?" the king asked Vicente with a smile.
