Captain Jade Hasegawa, former Master of Magic
The story's main character. A Starfleet Ranger, her exploration of the universe is cut short when something strikes her ship, making her do a forced landing in the Wolfswood, a few days away from Winterfell. When Eddard Stark and his entourage arrive to explore the landing zone, she is thrust deep into the mess that is Westerosi politics, even as she tries to remain aloof and, at the same time, seeks proof of a danger that threatens not only Westeros, but the entire galaxy...
- Apocalyptic Log: She begins writing her log because she is not sure if she will be found by Starfleet before dying.
- Beware the Nice Ones: Just about the nicest person present. When pushed, also the most dangerous. She has a beam weapon, drones, shields and air support. And she will use them if pushed.
- Cloud Cuckoo Lander: She has her moments.
- Cluster F-Bomb: Jade has a very potty mouth.
- Court Mage: She finds herself promoted to this role for King Robert early on in the story. Her tenure does not survive the coronation of Prince Joffrey.
- Expy: Of Jade Harley from Homestuck.
- Fauxreigner: To soften the culture shock with people from a medieval society who would have difficulty to grasp the concept of spacefaring, she claims to originate from the unexplored land of Ulthos. She amps it up for Robert's benefit when she greets him and his party in Japanese.
- The Fettered: Jade's allegiance to Starfleet and personal morals mean she goes to great lengths to find a peaceful resolution to conflict whenever possible (she even makes a brief attempt to negotiate with the Others, before ascertaining that their Always Chaotic Evil nature leaves no choice but fighting back).
- Genki Girl: When she gets enthusiastic about something.
- Has Two Mommies: She has two moms and a dad named Sarah Hasegawa, Samuel Alvarez-Hasegawa and Theresa Itou-Hasegawa.
- Howl of Sorrow: When pushed a bit too far or stressed, she takes to howl to the moon.
- Meganekko: While her whole appearance and outfit look pretty exotic for anyone she meets, her glasses in particular (unheard of in Westeros, and which most assume to have been made in Myr) never fail to draw attention. They also double as Heads-Up Display.
- Mistaken Nationality: Nearly everyone who meets her for the first time assume her to be Dornish from her appearance (and those who don't believe her, like the Lannisters, keep referring her as such).
- Older Than They Look: Thanks to advanced medical technology Jade looks about 18 but Word of God is that she's actually almost twice that age (35, to be precise).
- Only Sane Woman: Of the notable characters introduced so far, Jade is one of a tiny minority who are more concerned about the fact that Winter Is Coming and that the Unbidden are massing in the North than bickering over who gets to sit on the Iron Throne.
- Outside-Context Problem: She's a big one for all of the Seven Kingdoms. Between her ship, her tech and her attitude, she becomes a player of her own in the Game of Thrones.
- Psychic Powers: She can detect others, communicate with and receive visions from the Weirwood Trees, though she is not fully trained.
- Sexy Mentor: Sarella certainly thinks so.
- Ranger: She's part of the Starfleet Rangers, who are the ones that boldly go where no man has gone before.
One of Oberyn Martell's bastard daughters, who joins the Order of Maesters by disguising herself as a man with the alias Alleras. When Jade visits the Citadel, she decides to make Alleras her apprentice.
- Action Girl
- Badass Bookworm: A maester by trade, she's nonetheless quite capable in combat.
- Mentor Ship: By the start of the second book, Sarella has developed quite the crush on Jade.
- Psychic Powers: After assisting and participating in Jade's Weirwood experiments, Sarella has started developing Greenseeing abilities of her own.
- Sdrawkcab Alias: Her alias Alleras is her real name spelled backwards.
- Sweet Polly Oliver: She disguises herself as a boy since women are not allowed to be Maesters.
- Tomboyish Name: Jade shortens her alias as "Al", a nickname that sticks even after she no longer makes a mystery of her actual identity or gender to her.
