First Plot : So for the plots I was thinking to do some sort of band of rogues, but they're having help with a couple of "evil" cats within the clans. One including Stoatleap, the Windclan deputy. They could be collecting cats and bribing them to join them or train with them by their problems or pasts. The clans don't hear of Starclan in a while, but still meet up at gatherings. Soon enough, the clans begin to become absent from the gatherings, because of the sudden deaths occuring and lack of trust. One clan finds scents from the other and dead prey, thinking it's the other clan and attack, causing a riot to outburst. The clans take sides in alliances, Shadowclan with Thunderclan and Riverclan with Windclan. Bloodclan would be left out of this with there own plot. I haven't thought of the rest is, but any staff can leave suggestions below on what they think could happen!
Next Plot : I'm thinking the next plot could have something to do with Skyclan, or maybe a split Skyclan, OR the tribe of rushing water and either one of them/the options have been chased away and given territory to the clans, but must learn to fit in and clans are suspicious etc.
Bloodclan could be messing around with the clans in a sort of way?
Bloodclan Plot (first) : For here, I probably got the most planned out. They have nothing to do with the clans in this first plot (mostly) and it's about Morgen being taken over by her daughter "Peril", who has her two littermates ruling by her side (Blaze & Riot). She turns insane over the overwhelming power given to her and practically goes on a murder streak. She's become horribly dangerous in the streets and now Riot thinks she's become too dangerous for his own liking. Riot plans a rebel attack and the whole of Bloodclan splits into three groups, Peril's followers, Riot's followers and Blaze's followers. In Peril's group are the loyal, mostly insane themselves about killing. In Riot's they share the same opinion on having a more organized clan that can help them more then Peril could. And in Blaze's cats join that don't want to take either side, and end up voting for Blaze to rule. In the end, Riot manages to kill his sister in a battle, taking over the rule with Blaze dead by Peril killing her first.
Again, please, comment below if you have any suggestions or ideas to help out with the plots!!
