Either Aedion or Cassian. Though probably Aedion, then Cassian and lastly Rowan.
Somehow if I'd be in Erilea or Prythian I could trust these males the most and they would probably help. As for Rhys I'd be scared somehow but I can't explain why. And sorry Azriel but I would be terrified... Because of the Shadowsinger ability and his scars from his evil family.
