Actually, that'd be kinda nice, considering Leslie Hall dropped out of this and originally Luna was going to be part of 'Team Veritas' - Rosalina's personal squad.
Just brainstorming, but Grane could also take special interest in Luna because she's icredibly powerful for her age. So after Luna joins Rosalina's squad, Grane could then almost immediately pull her out of the squad for some reason relating to that.
Though, Luna won't be joining the Rune Knights until she gets back to Fiore anyway. And it's just an idea.
Okay, just tell me when you're interested or have any other Council related ideas.
