“"I mean, look at you guys. You used to be so cool. And now you're just . . . Eh Well, I'll be off then."”
—Stina Heks, in Book 3: Everblaze
Stina is an elf who is known as the school bully at Foxfire, and most people call her evil. In Lodestar, it is revealed she is an Empath, like her mother. She and Sophie have a strong rivalry and Stina constantly tries to taunt and bully her. But in Neverseen, readers find out she is willing to be a bit nicer to Sophie if she can heal the gnomes. She is the daughter of Vika and Timkin Heks.
She is described as being extremely tall with a beanpole body and frizzy, brown curls. Stina has a high pitched, wheezy laugh.
- TIMKIN (father)
He had been in Exillium for pretending to have a talent so he could get in the elite levels, but has earned his way back. He works with unicorns, trying to earn a way into the Nobility, and he works with the Black Swan.
- VIKA (mother)
She works with unicorns.
- SOPHIE (enemy)
Stina isn't very kind to Sophie, believing Sophie is of lower social status. She tells Biana that by her and Fitz being friends with Sophie is ruining the Vacker name. In book 1, Stina is the first to tell Sophie that Biana first befriended her because Alden forced her to. In Neverseen, Stina becomes somewhat less hostile, and tells Sophie that if anyone could fix things, it would be her.
- DEX (enemy)
Dex and Stina have a long-running battle of mean pranks on each other. Dex made Stina bald and in return Stina put a muskog in Dex's locker. Dex also gave Stina a beard, which was added as an extra pranking feature for her in the hairoids. Stina constantly holds the fact that Dex's parents are a bad match over his head.
- MARELLA (friend / former foe)
Marella used to hate Stina in the first and second books of the Keeper series but eventually became friends with her during Everblaze when Sophie did not really pay attention to her. However, in Lodestar, Marella is envious of her when Stina manifests as an Empath, and pulls away from Stina as a result.
- MARUCA (friend)
Maruca and Stina became friends after Biana started hanging around with Sophie because Maruca felt abandoned by Biana. She was the one that told Stina the real reason Biana became friends with Sophie, which caused Sophie to temporarily break up with Biana.
