It was a good thing that Luna slept longer than usual this time, as Laura wanted to do a lot of sightseeing inside the city, and not just shopping. They had a lot of unique and historical architecture that the Dragon hadn't seen before, from multiple cultures and even other places, including the Celestial Realm, which Evangeline helpfully identified.
The moment they entered the Library, Luna was already rushing towards them, barely slowing to wave at the archers as she passed them.
Luna took Laura and Moana into a side study room to talk, while an exhausted Evangeline came to see how Cain was doing.
"You know, even though Seraphim don't sleep, I don't think I have ever felt this exhausted before. I wonder if the Companion bond granted some sort of hidden bonus to mental fortitude?" The Seraphim complained, flopping down on top of Cain and letting her wings hang down over the side of the chair.
