Kathy Castellan

Kathy Castellan is the half-sister of Luke Castellan.

Before the Rebellion
She used to stay in Cabin 11 with all of her other half-siblings. She likes stealling things with the Stoll brothers and is always pickpocketing small items (money, daggers) which made her an expert in pickpocketing. She was very nice, warm, and bubbly girl. That all changed when she found out that her brother was killed by Percy Jackson.

Quest for Backbitter
Hermes tells in a prophecy that Kathy needs to find Backbitter.

Present
She's very mean. Always gives off a meanacing glare that will kill somebody just by looking at it. She never smiles at all. She doesn't laugh. People working for her says that she has this dark arua around her.

Inherriting Backbitter
Hermes sent Kathy on a quest to find her brother's weapon Backbitter. She then uses it as her own instead of putting it in the relic attic.

Swordsmanship
She has the same abilities as Luke's.

Relationships
May Castellan: It's horrible.

Hermes: It's also horrible.

The Rebellion: Horrible, but they somehow manage...

Percy Jackson: She loathes him for killing her only considerable family. To sum it up, she wants revenge.

Peppermint Sweets: They are "Best friends" in Kathy's perspective. She doesn't know though, that Pepper is a spy for Camp Half-Blood.
