Featherstream's Warning - Prologue

( Yes I know the parts are short but I'm too lazy c: )

Featherstream - light grey tabby she-cat with blue eyes
Artist for cat on cover: unknown (but credit to them!)

Featherstream is a new warrior of ThunderClan. She knows that the clan might not survive leaf-bare, and she has to go on many patrols to find food - and sometimes at night. Once night when she stays in her den, she has a dream, or should I say, warning: Everybody thought the evil, danger, and battles were over, but the darkness hasn't been put away for good. Evil is rising one again, but far more tougher. (I won't spoil what it means)
