Gratuitous "ê", here, for the Cêpan, still pronounced Se-pan. They're the keepers of the Garde just because. All of these technically count as The Mentor, but some are more competent than others.
- Alternate Landmark History: The 7/7 bombings (Britain's 9/11, if you didn't know) are implied to have been part of his fight with Mogadorians.
- Britain Is Only London: Played with. The extremes of the Highlands and Ireland are lived in, before London seeming to be the only other conceivable place in Britain to move to.
- Scotireland: Lives with Maggie in Ireland and then Scotland, before killing a Mog scout in the Highlands and having to immediately relocate to London.
Said to be from near the forest on Lorien, so goes to live in the forest in Kenya and/or 'The Congo'. The only unnamed Cepan.
Played by Reuben Langdon (film).
- Gory Discretion Shot: Yanked through the door of their hut by one of the lizard glider creatures.
- Impaled with Extreme Prejudice: In the book. In the film he's eaten by a piken or a kraul.
- New Media Are Evil: How he was found in the middle of a jungle is All There in the Manual: An Intrepid Reporter visited this place looking for a story, noticed Three's strange scars and wrote about it: exotic plant marks or local ritual, who knows? Well, the Mogadorians.
a.k.a. Brandon. But mostly Henri, he is Number Four's keeper.
- Dead Man Writing: His letter to John.
- Parental Substitute: John says, "We always joked about it but you were my father, the best father I could have ever asked for."
- Shipper on Deck: Like Arun, Lyn, Liren, and Lara, really wants a Childhood Friend Romance to spring up between Four and Six.
- Meaningful Name: Rey (his Lorien name) means 'King', from the Latin.
Number Six's guardian, she taught her all about Lorien and fighting and they stayed on the run in America, but still allowed Six to have a 'normal' life. Responded to Two's internet post and so got killed.
- Hypocrite: Tells Six she can't take the name 'Starla' because it draws attention, when she's called Katarina.
- Informed Attribute: In Six's Legacy, Six worries that Katarina's name would attract unwanted attention if she continued to use it in Mexico. Other than the odd spelling, though, Katarina is a perfectly acceptable Spanish name, so there is really no reason to worry about it.
Seven/Marina's guardian, was known as Adel on Lorien but went through many names on Earth before Adelina. She kept Marina entertained travelling through Europe for a short while before pretending that Lorien was just a big fairytale and becoming a nun.
- Heroic Sacrifice: Upon realizing she did so wrong by Marina, Adelina takes on the Mogadorians so Marina can escape.
- I Have Many Names: Took on a new name in each country. Two in France.
- Nun Too Holy: Eventually, but only mildly.
- Refusal of the Call: Crayton visits her to begin gathering the Garde but she turns him away.
- Justified to an extent by the fact that even if she had maintained her will and was fighting for Earth and Lorien, it would be hard to believe that another ship had managed to leave and arrive at Earth. Also, she would acknowledge, deep down, that pairing up would break the charm and so Marina - Number Seven and so still three away from death - and Ella, claiming to be Number Ten and so seven away, would not have the security they did.
- Starting a New Life: Her intentions in Spain.
- Love-Interest Traitor: Lola, like Maddy and Wade, is working with the Mogadorians.
- It's remarkable that out of the four Lorien who have an Interspecies Romance, three know the Mogs and sell the person they (supposedly) love out.
Nine's guardian, he sets up a safe house in Chicago that Nine can always return to after his "teaching gigs". Very young to be a mentor, and gets on well with Nine. It is implied that his youth and love of when things go wrong made him an inadequate mentor for one of the Garde.
Played by John Reynolds (audio books).
- Home Sweet Home: Makes Chicago into the love of Nine.
Unofficially Ella's guardian, as she was just born when the Mogadorians attacked Lorien. Becomes a surrogate father to her and all the others. He is the last Cepan left alive once Henri dies.
- Dead Man Writing: Has a note for Ella in his pocket for when it happens.
- Parental Substitute: To Ella who calls him "papa".
- And tells Six, Seven, and Eight that he will be theirs since all their Cepans are dead.
Played by Cherise Boothe (audio books).
