Both the group that sent the fox and the group Percival's father and that black knight belong to oppose the Four Knights of the Apocalypse? Or did I misunderstand?

And yeah, hopefully Percival will get growth spurt that lets him fill his grandpa's cape.

And how come the Four Knights are prophesied to destroy the world? Aren't they supposed to be the heroes? Either they'll just destroy the world as the people in the story know it which is essentially the same as saving it, or that part of the prophecy is wrong because it was told by people who oppose the Four Knights.

Edit: Could be that the fox meant that it was sent by a group that opposes the group of knights Percival's father and the black knight belong to. This seems likelier, otherwise the fox wouldn't try to help Percy.
