- Authority Equals Asskicking: As the Captain of the Queen's guard, he is officially the biggest badass in Faerie.

Sholto (AKA "King of Nightmares", "King of the Sluagh", "Creature")
- Defrosting Ice King: He comes a long way from the awkward young king in the first book.
- The Good King: To the sluagh. Ironically, a hell of a lot better ruler than Andais or Taranis.
- Half-Human Hybrid: Half-sidhe, half-nightflyer, actually.
- Royals Who Actually Do Something
- Surprisingly Sudden Death
- Ax-Crazy: She got her start as a goddess of battle, and can become overwhelmed with bloodlust.
- Blow You Away/Casting a Shadow: She's called "The Queen of Air and Darkness" for a reason.
- Card-Carrying Villain: Andais seems to relish her role as Evil Queen, and furthermore believes it's representative of what the Unseelie Court is and should be.
- Even Evil Has Standards: Andais has repeatedly shown herself willing to sacrifice her own happiness for the good of the Sidhe. She loves her son beyond reason, but she almost lost her shit when she found out Cel commandeered her dead brother's guard as his harem. When she realizes she is infertile, she decides to abdicate in favor of whichever of her heirs can create a child first, knowing that she has no right to hang on to the throne in a Fisher King situation.
- God Save Us from the Queen!: Yeah, she's still a sadistic tyrant, though.
- Yaoi Fangirl: In lieu of having her guard have sex with her, she sometimes orders them to have sex with each other, and watches while they do it.
- Ax-Crazy: Just like mommy...
- The Caligula: ...Only worse.
- Evil Prince
- Momma's Boy
- Royal Brat
- Villainous Crush: He has a really squicky obsession with Merry.
- Evil Uncle: After his Moral Event Horizon.
- Fisher King
- Light 'em Up/Master of Illusion: Just as Andais is The Queen of Air and Darkness, he is The Lord of Light and Illusion.
- Light Is Not Good: He's all that is bright and shining and beautiful. And he's the Big Bad.
- Meaningful Name: Taranis = "tyrannis"/"tyrant". Even Andais is a better ruler than he is.
- Villain with Good Publicity
