[@Adorabadass] I know you're still working on this, but I'm letting you know now, if your character is too old to be a teen on a caravan, but is of adult/fighting age, he's going to be assigned to a frontline position.

Older, more experienced characters are expected to have a proper balance- a physical balance. If your character is going to be a caravan guard, he's likely going to be either crippled, past his prime, or both.
