Carnelius is the younger of the three, and the most carefree - he mostly just lives his life of a prince with gusto. He hasn’t done anything relevant political-wise, mostly just enjoying the luxury while getting homeschooled by tutors. He is the most aware of Agata’s abandonment of them over the kingdom, however, and does try to help Diaspro in any way he can, even if she rejects the help 99% of the time. He’s a low-level Caster - sharing a Source of Earth with her sister, though he hasn’t pursued magic much. His title is Caster of the Sands, as that is his focus.

Flint meanwhile is the oldest, and he acts as an ambassador for the kingdom in trade agreements, as well as overseeing most of the internal politics - he acts as Agata’s advisor from time to time. His job is incredibly demanding and he’s away on work travel most of the time, so he’s not aware of most of the more personal stuff going on. He thinks Dia should be focusing more on her role as future Queen rather than her powers as a fairy so that their mother can finally rest (and shut up), and considers Carnelius a lazy bum who’s just wasting the tutor’s time and the kingdom’s money. He can’t use magic, but does live off a mix of coffee and anti-sleep potions.
