Alright made some plans in the mega au instead of sleeping I've got:
Sandstar w/ her savannah cat deputy Fireheart
Adopted Squilf and Leaf (for the sake of the other clans and ThC's gene pool I'm only allowing one wildcat hybrid)
Holly still flunking out of med cat school, but being a stellar warrior apprentice and also making the warrior code her personality for the first year of her life
Chimera Jaypaw in windclan with his brother (half-brother but they don't know that yet) Breezepaw. Inseparable and insufferable
Crowfeather still sucks but he also clearly favors Jay which is...hmm....
Nightcloud needs some goddamn character development. She joined a coup for christ's sake.
Deputy Silverstream and the girl has been through the horrors...repeatedly. She got the role not because she was her father's daughter but because of her ability to survive the Horrors. Lots of drama in RiC btwn her and Leopardstar
Considering having Sasha stay in RiC
Medicine cat star marks and Leafpool going from Starclan's golden child to having a years long faith crisis (poor girl)
Riverclan Lionpaw who goes through many of the horrors, gets character development, and eventually (maybe) decides to become a med cat much to his clan's chagrin.
The Clan Olympics being a yearly thing instead of being done once. The first year Sandstar lets her mate hunt apprentices for sport... safely, of course.
No plans for Sol rn, not a fan of conflict coming from outsiders instead of within the very obviously unstable clans.
All the clan's founders, except Skyclan, were women + some kitty cat misandry for spice
Evil -> morally dark gray Leopardstar
The Ancients have been done away with for the moment. They only exist as the founders of the tribe.
OneFire one-sided marriage + divorce arc
I have seen multiple fics and aus use a "we don't talk about exiled or executed people or traitors in general so they'll fade in memory" thing in the clans. That's genius and I'm stealing it. It makes the dark forest trainees make sooo much more sense.
ThC having a massive predatory cat that's like thrice the size and strength of the average clan cat in a deputy role + having the largest number of cats puts them in a very unique position since no one with brains wants to fight that. So they end up being sort of mediators in a very morally questionable way.
Speaking of, Fire genuinely considering killing someone twice as an apprentice and having to be physically stopped the second time is... certainly a trait that will be explored.
Tigerclaw really wanted that giant cat on his side.
Lionblaze (to be renamed) gets no bitches.
More kitty culture specific to each clan. We're bringing back tunnelling.
Blackstar... is there. And a not insignificant amount of RiC has beef with him.
Making the cats slightly more cat-like. ThC and ShC have unlocked the ability to land on their feet.
All of these are of course subject to change
