Juniperkit, Jaykit, and Stormkit are born into ThunderClan by their mother Bluefur. All three kits survive their birth, and Blue brings them to ShadowClan to live with their other mom Yellowfang, who has to give the litter to Lizardstripe (just pretend timelines make sense). Lizardstripe is in a super difficult position— she doesn’t want kits, never really did, but got pregnant, and now three more kits are being forced upon her by the Clan leader Raggedstar. She’s not a good mother, and honestly who can blame her? Well. The majority of ShadowClan can, I guess. But then Storm and Jay die from a sickness, Juniper blames Yellowfang and Raggedstar— Yellowfang for not healing her brothers, Ragged refusing to let Yellowfang treat Storm and Jay because they were too far gone. The ghosts of Jay and Storm kind of follow Juniper around, and they stay kits whilst Juniperkit grows to an apprentice, and then a warrior— Juniperfall, perhaps? She discovers she has a power (instead of Jay&Lion having powers and Holly not, now Juniper has powers & Jay&Storm don’t) to… idk, see the dead? Fade into shadows/go invisible? Juniper is super protective over young cats now, but also has a grudge against Ragged and Yellow, due to her brother’s deaths. She becomes deputy, then kills Raggedstar by making him eat deathberries (👀 deathberries… woah… haven’t seen that before I’m sure… (looks at Hollyleaf and Leafpool) (looks at Yellowfang and Brokentail)). But after killing him… she can no longer see Jay and Storm. She can see other dead cats, but her brothers have left her. They are afraid of who she has become, and honestly, it scares her too. She becomes Juniperstar, and tries to fix her wrongs, but in a way where she actually is being kind of evil, but has a reason for being evil, protective, etc etc, stuff like that. She steals kits to raise them in ShadowClan to be safer, trains them from a younger age so that they’re stronger sooner and hopefully won’t die young (this backfires at a few different points probably). And then, timeskip.... well, not sure what happens in between, but similar to what happened with Brokentail, and as a parallel to what she did to Raggedstar, Yellowfang gets her to eat deathberries, and she dies. Alright that’s all I’ve got!
