Henlo! This is going to be a short theory thing, so yah! Oki so in chapter 13 of @9rainbowtails' comic, Tales Of Perfectheart, Goldenfur is possessed and is forced to tell Moonpaw (at the time) this prophecy: The one who allies with the breeze, Whom sends fear through fish and trees, Fading hope as one response, Throw away their jeers and taunts, Perfection threatens the newer days, Opens from the older ways, May be obvious on first glance, Never take the trusting stance, Don't allow them to ban, The only one who can save the clans. Now I think that "the breeze" is Windclan, and "fish and trees" is Riverclan and Thunderclan. "Throw away their jeers and jaunts" could be a reference to a future Houndfang where he is bullied by other cats. "Perfection" is probably Perfectpaw. "May be obvious on first glance" may mean something about what is happening with Dark Forest and Starclan (eg. May seem obvious that Df is behind it when their not). "Don't allow them to ban" could be Houndpaw.
This all goes to @9rainbowtails for credit, except art and theory. Thank you @Vaporeon_Moonspirit for pointing the Hounpaw thing out to me, that makes more sense.
