Penelope

Penelope is the sister of Atticus' friend, Celeste. Atticus and her don't get along well for a majority of the beginning of Champion Batticus, but eventually resolve their conflict. She is a part of the questing party to the Airways.

Penelope is very quiet and reserved, not speaking much unless spoken to first. She enjoys to read and talk about culture and history and takes her academics very seriously.

Champion Batticus
Penelope is first seen visiting Atticus in the hospital with Celeste and it is made clear Atticus does not like her. She is seen again when the quest party is first assembled, though she doesn't speak much. Next she is seen when Atticus spends the night at Celeste's house when they have breakfast. She doesn't speak, instead reading a book. When they reach Steadfall Penelope accepts a tour of the town by Oriole.

The next morning Penelope complains about her feet hurting and Atticus and her get into an argument. Atticus leaves after Osprey insults him, but comes back and apologizes to her during lunch. Afterwards she apologizes to him for treating him poorly as well and they end of talking for quite a while. Penelope tells Atticus about how poorly House Harpy treats 'lower species' and says not to trust Osprey. Later in the evening Penelope talks with Trylon about Sequoia Sanctuary, the culture and history interesting her.

Celeste
Penelope spends a lot of time with her sister, sometimes unwillingly going on adventures with her and Atticus. Though she cares about her sister, Penelope criticizes her for not putting effort into her academics, only caring about magic.

Count Castiel
Penelope isn't as close with her father and acts distant towards him. When Count Castiel is talking to Mom he brags about Celeste and does not mention Penelope much at all.

Atticus
Penelope and Atticus don't get along for much of the beginning of Champion Batticus, but end up resolving their conflict after having an argument. Penelope bonds with him over talking about her interest in history and culture, something she doesn't get to talk with Celeste much about.

Trylon
Penelope gets aong well with Trylon and talks with Trylon about the history and culture of Sequoia Sanctuary.
