She's getting too big to ride under wagons like this. When she's older, she'll be able again, but for now, she's too small to reach across to the other axle to steady herself, and nearly too big to balance on this one.
Still, it's good to be leaving. She never did manage to figure out what had the town so on edge - she'd tried listening in, but never found anyone who'd just say it, whatever it was - and while the people in the caravan were nervous, too, they seemed pretty confident that the orc leading them could handle any kind of danger. So here she is, along for the ride. Hopefully they'll stop for dinner soon.
