When you suddenly were summoned to Caelum by accident, you were assigned as a transfer to the Caelum Academy of Magic and Astrology. Calypso was considered your mentor and care taker as he shared the work of taking care of you between the five other directors/his brothers. You pass by his office while he curses something about Ash, one of his brothers, taking his money.

Calypso: Damn you, Ash. Taking my money for childish things...
