Erin Hunter said this quote

A breeze stirred Dovewing's pelt, as is someone had walked past. She lifted her head an saw two figures standing just beyond her Clanmates. One was a badger with a narrow, striped face, the other a grotesque, hairless cat who's blind, bulging eyes saw nothing but everything. They met her gaze and nodded, just once. Thank you. Dovewing heard, quieter then a sigh. There will be three, kin of your kin, who will hold the power of the stars in their paws. They will find a fourth, and the battle between light and dark will be won. A new leader will rise fro the shadows. This s how it always has been, and always will be.-Rock and Midnight, The Last Hope
