Codebreakers

The codebreakers are a group of cats named by Bramblestar's impostor to have broken the code and must be punished.

Punishments

The impostor is incredibly adamant about punishing the codebreakers, first forcing Tree and Dovewing to go into temporary exile, and then forcing Lionblaze, Jayfeather, and Twigbranch to swear an oath of loyalty to him, with the threat of exile if they break the code again. The punishment for Crowfeather and Mothwing is yet to be revealed. However, the impostor strangely refused to let Squirrelflight take the oath, even though she offered and reminded him that she was a listed codebreaker. Despite this, when she informed him she was going to "atone" by herself, he tried to persuade her to take the oath, but she refused. He only ended up punishing her with exile after she realized he was an impostor.

Named cats and reason for their placement on the list

ThunderClan

• Squirrelflight, for lying to the Clans and pretending Leafpool's kits were her own.
• Lionblaze and Jayfeather, unknown. However, both speculate and believe it is for being born half-WindClan.
• Twigbranch, unknown.

ShadowClan

• Dovewing, unknown.

SkyClan

• Tree, for questioning the Clans' way of life.

WindClan

• Crowfeather, unknown.

RiverClan

• Mothwing, unknown.

Trivia

• Tree was neglected from the list of codebreakers in The Silent Thaw. During the book, it is made a point several times that no SkyClan cats were mentioned. However, Tree was eventually exiled and named as a codebreaker by Bramblestar's impostor. It is unknown if his name was added beforehand by accident in Lost Stars, or omitting it from The Silent Thaw is a mistake.

Quotes

"Then why isn't every cat named? Am I going to be punished because my mother broke the code? She was the one who had kits with a cat from another Clan, not me!"

―Jayfeather when he learns he is a listed codebreaker ^{The Silent Thaw}

Lionblaze: "Why should StarClan drag that up now? And what has it got to do with me and Jayfeather? Did we break the code by being born?"

Impostor: "It's pointless arguing. StarClan has spoken. We must obey them."

^{The Silent Thaw}

"I wish I knew exactly what I’ve done wrong, I'd happily own up to it if I did. I've only ever wanted to be a loyal warrior."
