This goes back to the other chapter, where Graylight had his dream.
Bramblestar crawled into his nest and dosed off. In his dream, he was hunting a pheasant. They're quite rare to find, and this one was quite plump. He was about to leap for the perfect kill but The pheasant was scared off by a voice.
"Bramblestar.." Came the voice, which belonged to the cat he thought was his daughter for so many moons, Hollyleaf.
"You'd better have a good reason for scaring off my pheasant." He mewed teasingly.
"Bramblestar this is serious." She mewed with a stern face. "The moon in the prophecy you know is Moonfur, Correct?" She asked. He nodded. "There's a new part to the prophecy." She sighed. "The Moon is rising it shall not Fall. When darkness meets light, there will be a battle that could kill them all." and with that, Holyleaf padded into the shadows.
Short, mini-chapter and thumbs up to you and a virtual cookie if you can guess what the prophecy means
