I have some idea for Ewan if you're interested.
I have my character
Angel, who I keep wanting to do a run away from home plot with her but all of her threads always die before they get anywhere >_>
I can see her not wanting to put up with the kid but being too nice to just 'leave' him somewhere and constantly reminding him she's older when- little does he know he is TECHNICALLY older than she! (and I'm debating revising her profile to give her some magic, but not sure :T )
I also have my Serenian Merchant,
Dylanna Swinden who would definitely take a young child under her wing if they needed it, though she has no magic of her own, she could help him get somewhere to offer him direction!
Or if you're up for some quirky adventures to help an antiquities thief, I do have my character
Aurora Jane who might fit the bill. Would be interesting to see her interact with a kid and possibly manipulate him into helping her get an antique relic or some such that's hard for her to access, but perhaps not for him?
