There is no good or bad, there's only weak or powerful. And I want to be powerful.

— Linus to his family

Linus Arcturus Mortan (b. 27 July – 3 August) was a half-blood wizard of the Potter and Mortan family, the youngest child and only son of Corvus and Astoria Mortan (née Malfoy-Potter). He was also the younger half-brother of Gwendoline Mortan. The son of a school governor and a journalist for the Daily Prophet, Linus grew up extremely spoiled, nosy and entitled, thinking very highly of himself and his family.  

Upon attending Hogwarts School of Witchcraft and Wizardry, Linus was Sorted into Slytherin House.

Personality and traits

"My friendship with the Mortans has always been productive. But Linus is not a reliable ally. He's a vicious boy who was raised to believe he was born with a crown on his head. And who could trust a friend like that?"

The name Linus means "flax" in Greek, possibly indicating someone who was blond or flaxen-haired. Some sources say it is Etruscan for "one who mourns." In Greek mythology, Linus was the son of Apollo, and a talented musician on the lyre.

Arcturus, also designated Alpha Boötis (α Boötis, abbreviated Alpha Boo, α Boo), is the brightest star in the constellation of Boötes, the fourth-brightest in the night sky, and the brightest in the northern celestial hemisphere. Arcturus is also part of the Spring Triangle asterism and, by extension, also of the Great Diamond along with the star Cor Caroli. Loosely it can be translated from Greek as "guardian of the bear."

The surname Mortan may have several meanings. It could be seen as a variant of the Scottish habitational name Morton, meaning from the farm near the moor. However, it is believed to be a surname of French origin, taken from the old French word morte meaning "death" or "to die".


Linus: Xanthas, may we talk, one ten to another?

Nancy: I'm doomed!
Linus: You lived a good life.
Nancy: I'm not even a teenager yet!
Linus: I said good, not long.

Linus: I've been watching you... all excited like a little boy who's just picked the lock on his father's Jodhpur armoire.
Odysseus: Linus, mate, your experiences are not universal.

Megaera: You look like you fit in perfectly.
Linus: I just make a lot of noise so they don't ask me any real questions.
Megaera: What are you afraid of them asking?
Linus: I'm afraid that would be telling.
Megaera: No, really.
Linus: Maybe I'm afraid of people finding out I'm not who they think I am.
Megaera: And who are you?
Linus: I don't know yet.
Megaera: If you could, would you just just get as far away as possible?
Linus: No. I think I'd like to find somewhere that feels like a real home.

  • Linus's surname Mortan is derived from the French word morte, meaning death or to die. While this is ironic as members of the Mortan family usually are thought to live very long lives, this may be potential foreshadowing towards his own death, as he, his wife and his daughter (both of whom also took the name) died after meeting terrible fates.
