Carth set his pack and Ash's into the wagon before he goes and grabbed his horse to add to the front with the assassin's horses. Altoron helps set Carth's horse up to the wagon. Once that happens Carth gets into the wagon. 

Orion gets his pack and bag into the wagon with the help of Carth and then gets in. Once the assassins settle the horses, the brothers get into the driver seat as Altoron gets in the back. 

Once they were ready and the snap of the reins, they left the fort and back into the light of day and open field and mountains.
