Do you think SkyClan will last? I mean, they're new and are vulnerable to a night attack when they're Daylight Warriors are back at their twoleg nest. And at anytime the Daylight Warriors might go and say, "Eh, we're going back to our twolegs. Much better there." Until they get to be at a good strength, I find multiple faults with them.
I know the chances aren't likely for this, but if they do, they could join up with the bad rogues from SD and then come over to SkyClan and be like, "Give us your territory. We're stronger and have more cats then you do."
Cats could all of a sudden be like, "Wait, I'm better then this! I should create my own full-time clan with no Daylight-Warriors and take over SkyClan!" Sharpclaw would most likely do this because he is, in my opinion, he is the strongest warrior in all of SkyClan. Or more cats who are actually half-decent fighters could be a Sol and then end up betraying them and taking over SkyClan.
Leafstar goes over the edge
Leafstar might go crazy with all the fighting going on about how Daylight-Warriors are eating there food at home and in the Camp. Or she might just give a cat the weirdest name ever, like I personally don't get the name "Billystorm". I know his kittypet name is Billy, but she could've called him something like Billyfur because for some reason his fur looks like a goats fur to me. *Is totallly not crazy* Or she might decide to become a kittypet and live the rest of her life peacefully after a really violent battle.
Lack of Self-Confidence
Name says it all. Leafstar was always worrying about a decision she made, and whether it was good for SkyClan.
Something like Twilight
If a badger attack happens, they're pretty much screwed.
I think they will barely survive, because these things have very little chances of happening. First Blog ftw.
