Warrior Cats: Whispers of the Dark Forest.

Backstories of the Dark Forest Cats

Blizzardwing: He'd do anything to protect Shadowclan, not above murdering enemies in battle, responsible for both murders of Brackenwing

and Stonewing. After his own mother wasn't avenged in battle, he grew the mentality that it was no big deal. When it came to protecting his clan, it wasn't always against enemy warriors, sometimes he considers the threat to be coming from within. When Cedarstar was growing too old to run the Clan but wasn't going to retire, Blizzardwing decided Shadowclan needed someone younger. So during a time when prey was scarce, Blizzardwing convinced Cedarstar, it was worth the risk of hunting in the carrion place. When they split up to hunt, Blizzardwing was right out of there. As planned, when Cedarstar returned to camp, he was sick with the Carron disease and he couldn't be cured in time.

But Blizzardwing's story wasn't over. After losing 2 kits to Brokenstar and being banished with the rest of the elders, Blizzardwing decided to take matters into his own paws. Recently, his only surviving daughter gives birth to a litter of two: Blossomkit and Swampkit. Thinking they're on a death sentence anyway, Blizzardwing decides to just kill them himself, saving them a more gruesome one at the claws of Brokenstar. So while driving out Windclan, Blizzardwing snuck onto the battlefield, with the help of the warrior, Deerfoot, they secretly glided the kits away from the fighting. But as soon as they were alone, they finished them off quickly. Though Deerfoot's motive was to send a message to Brokenstar - That appointing underaged kits is pointless.

However, realising Brokenstar didn't care for the litter's deaths, Blizzardwing decides to kill him directly. Though Deerfoot bails out, convinced it would end in their demise. And he was right. While Brokenstar was in a training session with his underaged apprentices, with no other warrior around, Blizzardwing attacked. With an advantage of surprise, Blizzardwing managed to take one of Brokenstar's lives. The white elder had convinced himself that Brokenstar only had one life, refusing to believe Starclan would grant the evil tyrant nine lives. Yet to his horror the brown tabby began to stir again, tearing the elder to shreds once given life again.

Deerfoot / Tangleburr: For revenge of their constant torment of him as kits, Brokenstar would relentlessly overwork his foster siblings, alongside their parents when he became leader. Soon, their father, Mudclaw fled from Shadowclan and their mother, Lizardstripe, was dying of greencough. Though Brokenstar refused to give her any catmint, claiming it was a waste. To save their mother, both siblings went about in different ways. Tangleburr did everything to impress Brokenstar, thinking he'd eventually award her efforts with the catmint. Meanwhile, Deerfoot refused to suck up to Brokenstar, instead trying to steal the herbs from other Clans.

Eventually, Brokenstar was on the verge of giving Tangleburr the catmint. Only on one condition – She had to kill a cat to prove she was truly loyal to him. She agreed, killing Lionheart in battle. Deerfoot tried dragging her off her victim, so she could retain her innocence, but it was too late. This put a strain on the siblings' relationship: Deerfoot was disgusted she follows Brokenstar's order to kill someone. Meanwhile, Tangleburr was angered that her brother considered Lionheart's life more important than their mother's.

Now that it mattered in the end, as Lizardstripe died the same day as Lionheart's murder. Thinking Shadowclan was a lost cause, Deerfoot tried to sow the seeds of rebellion. He teamed with the elder Blizzardwing: killing Dawncloud's litter, thinking they were saving them a gorier death under Brokestar's claws. However the two deaths didn't have an immediate effect on Shadowclan, who'd become numb to so many kits' deaths. Growing impatient, Blizzardwing tried killing Brokenstar himself without Deerfoot's input, which cost his life.

When Brokenstar and his followers were driven out, Tangleburr was among them. Deerfoot yelled for his sister to be given a fair trial but no one listened to him. Even being accused of being Brokenstar's follower himself, forcing him to remain silent out of the threat of exile. With his parents and sister gone, it was making him bitter and cold. So while they were separated, Deerfoot and Tangleburr relationship became sour and distant, their loyalties forced separate ways. Since they weren't fighting for their parents anymore, they began focusing on self-preservation.
