Straight to the capital! It's been a year since Sara traveled to Hydrangea, the hometown of her guardian Nelly. She's trained all that time at the Apothecary's Guild, and soon she'll be an apprentice no longer. That's when Nelly's father, Riot, suggests that she make a trip to the capital to introduce herself to the king. Nelly and Chris are along for the ride, with Nelly traveling to hunt migrating dragons and Chris tagging along to test a new drug he's developed as a dragon countermeasure. As luck would have it, Allen and Kuntz are coming too! However, there seems to be something strange about Allen... What trouble will they find waiting for them at their destination?
