Luke Castellan: zodiac sign and birth chart

Luke Castellan has no canon birthday. The books never give one. Read from his personality, he's an Aries. Sun, Moon and Mercury all sit in the same sign: the swordsman with the charming grin, the scar on his cheek, and the camp's best sword fighter. A Leo rising makes sure everyone is watching.

Birth chart

Luke's chart at a glance

No canon birthday, so this is NEBO's take, read from his character.

Mostly fire. 4 of his 6 placements are fire signs.
Double Aries. Sun and Moon in the same sign, about 1 in 12 people have that.
About 1 in 37 birthdays get Luke in the app's Percy Jackson world.
Other Ariess here: Dionysus (Mr. D), Silena Beauregard and Piper McLean.

NEBO's take

No birthday in canon. His personality says Aries.

We ran Luke through the same model that matches people to characters in the app, and looked at which chart gets him most often. It reads him as fire first: quick, charming and ready to act before he thinks it through.

NEBO's take

Aries SunRead from his personality

Sun CanonNot in canonNEBO's takeAries
Aries goes first. He is the confident counselor of the Hermes cabin, the one who teaches Percy to hold a sword when the new kid doesn't know which end is which.
Moon CanonNot in canonNEBO's takeAries
An Aries Moon feels everything at full volume. Luke never talks about the scar on his face, the reminder of the quest that went wrong.
Rising CanonNo birth timeNEBO's takeLeo
No birth time in canon. First impression, Leo style: a grin, a relaxed stride and the camp's best swordsman, walking like he owns the arena.
Mercury CanonNot in canonNEBO's takeAries
Aries Mercury says it straight and says it fast. When he talks about the gods, he doesn't pretend to like them.
Venus CanonNot in canonNEBO's takeTaurus
Taurus is loyal to the people it has already chosen. Luke, Thalia and Annabeth ran together as kids, and the older boy kept the younger two alive.
Mars CanonNot in canonNEBO's takeGemini
Gemini Mars wins by getting around you. He is a trickster's son, and in a sword fight he's the one who never stands where you expect.

What canon does give: the camper everyone looks up to, first in line and first with a plan. An Aries answer is to lead from the front and make it look easy.

How he shows up

Why he's like this

Aries is the sign of nerve, leadership and acting first. Luke hits every one of them, in scenes fans know by heart.

CoreAries Sun

Teaches by doing
He runs the sword lessons for the newcomers at camp, patient and cheerful, and nobody in the arena beats him.
The Lightning Thief
FeelingsAries Moon

Wears his failure on his face
The scar across his cheek is a souvenir of a quest to the Garden of the Hesperides that went wrong, and he won't talk about it.
The Lightning Thief
First impressionLeo rising

Everyone looks at him first
He is the counselor of the Hermes cabin, and the kids in it follow him like he's a big brother. His smile is a big part of why.
The Lightning Thief
LoveVenus in Taurus

Looks after his own
Annabeth remembers running away from home with Luke and Thalia when she was seven. The older boy kept the two of them alive on the road until they reached camp.
The Lightning Thief
CoreAries Sun

A grudge against the gods
When Percy finally learns who stole Zeus's lightning bolt, Luke explains why: he thinks the gods ignore their own children. His father Hermes is a big part of that anger.
