Her and her sister's life could very easily have been cut short at a very newborn age. Hunter could not accept the fact that she was pregnant with Wpelt, so she decided to leave the kittens to fate, since the kittens were still blind and could not protect themselves from wild animals in any way. But the kittens are found by a medicinecat named Flowerflight from Mistyclan. The kittens' lives were saved, Flowerflight brought them to the clan and the cats of this clan were happy to see the replenishment of the clan. Aspenkit and Petalkit got their first names then and grew up in this clan. They settled down pretty quickly and knew from childhood that they were adopted.

Aspen became a good and successful Warriors, but she still talked a lot with her sister. Until HunterFace appeared in the clan. Aspen did not recognize her mother, who abandoned her as a child, but reacted rather suspiciously to her appearance. Hunter was well received and they really decided to help her, but during the time one of the cats named SandSong dies. It was really strange, but no one suspected Hunterface except Aspen. One night Aspen decided to follow Hunterface and noticed Hunter hiding poisonous berries by the lake. Then Aspen was stunned by what she saw and wanted to tell everyone about it, but did not have time. Hunter grabbed her and stuffed poisonous berries into her mouth, trying to drown her in the lake. There was a duel between them, but Aspen quickly weakened due to the poison, which is why she lost the battle. At that moment, Hunter confessed that she was her mother and threw Aspen into the lake. Due to the incredible surge of emotions, Aspen went under water while dying. Her body was weak, but thoughts flickered in her head, and something very strange happened here. The ground cracked under the water and Aspen's body was pulled into this crack. Then Aspen woke up in another creepy world. Aspen got scared, she tried to get back into the ordinary world, but her body died, Which is why her soul separated from her body and Aspen penetrated into the ordinary world in the form of a spirit. This gap into another world closed, and Aspen remained in the form of a spirit. But in the form of a spirit, her horns appeared, the color of her paws and eyes changed. Aspen was devastated, but realizing that her sister and others were in danger, Aspen, in the form of a spirit, decided to enter Petal's dream to warn her sister about the danger. At that moment, the sisters decided to unite and Aspen promised to help Petal face the danger and protect her. Thus Aspen was connected to the Petaltail body.
