Hot take: We've had enough prophecies
Is anyone else a little tired of EVERYTHING being decreed by fate and the ordained declaration of StarClan?
For starters, half of them literally spoil the endings of their arcs. You're telling me three must become four to stand against the darkness? Gee, I wonder what's going to happen in the rest of OOTS. It makes me wonder if these guys even have free will - like, what would have happened if Alderheart never went to find SkyClan? Would everything else not happen? If so, why didn't StarClan just say "hey, don't go there, and if you do, don't trust this Darktail guy..." and save everyone a lot of trouble?
Also... like... the characters will get a prophecy foretelling death and destruction, and proceed to do basically nothing for pages or even entire books (save for whatever plot-mandated twist or cliffhanger happens in the meantime). It's a coinflip whether they even tell anyone else about the possible END OF THE CLANS (for real this time, we mean it!)
I don't know. Can we have an arc that doesn't tell us who the important character is and how it's going to end? It doesn't actually help the tension of the story.
