Hey, here's something to think about:
Where did the Dark Forest come from again?
Think about it: Where was it when Firepaw first came in? When the second arc started, it just magically appeared, and you can't just say that it poofed in, because it was in Crookedstar's Promise, but it never came in in the first arc.
This is kinda short, but i had to get that off my chest.
