Hrmmmm... Are we going to be able to find some kind of clothing along the way to up our disguise game? I feel like a lot of us probably look kind of ragged. If finding some kind of dress is possible, Amaia will want to go as Kouri's handmaiden. I think I'll have to do a little collab with Mikan to see what she thinks about that possibility before deciding. If that doesn't seem likely then she'll want to go as a bodyguard.
Ignas will want to be a noble's commoner entourage as their personal secretary/scribe/treasurer/whatever. HOWEVER, if nobody else is around to fill in for second noble slot (say Kad is too busy to make Samuel take on that burden), he could be convinced to play the role. It would require convincing though, because Ignas would never dream of volunteering for the job. :P
