"It's not spoiling. Birthdays are for exchanging gifts." Galahad hands this one down to her.

It's an illuminated bestiary, almost identical to the one he loved from the nunnery, except that this one also includes animals that might only be familiar to some people at the mansion -- there are creatures from the worlds of Lan Wangji and Wei Wuxian, Tress and Asmodean, Aleksander and Nina. It was his favorite book when he was a child, so it seemed right for Sunny.
