The thunder falcon landed inside the city and watched over the mage taking out rations from the storage bag. Valerian had accumulated a meager some of the money, and his clothes and medicines were mostly stored in the magic bag. So Linea trained her eyes on the mage intently.

Kunta asked back, "Why do you say so, Your Highness?"
