That's a good point and it's quite easy. Araspeth, a reader of scriptures, sees Olive's magic and goes to the Queen—also a reader of scriptures—to tell her of it. The Queen recognises the light magic as Yuuna and freaks out. She seeks to end Olive with her own hands before she masters Yuuna's power and its too late.
Perfect! So the next place Araspeth goes to is back to the castle to enlist the queen.

Yes, I would like them to meet and overcome obstacles on the way. And in so doing, they become closer to one another.
