I think you should stop asking for 'rogue wizards' as that gives off the wrong impression XD
Sounds like to me you're looking for people to arrest rather than recruit
I do see your point. However looking at it through Rosalina's perspective; there's no reason for Nolan to know why she's looking for them. It seems that looking for rogue wizards who have committed a crime is a less pathetic excuse than 'We literally have no other options for recruits atm can you smell our desperation?'
Besides, it might make it more interesting this way. Rumor starts going around that the council is supposedly arresting Rogue Wizards could make for some interesting interactions when Rosalina and the other Council Members find them. One big misunderstanding.
