Fireclan

A fan-made book from Warriors by Erin Hunter. This takes place after the legacy of Firestar and the original four clans: Thunderclan, Riverclan, Windclan, and Shadowclan. Not long after, actually. The clans are now known as Clawclan, Iceclan, Pawclan, and Fireclan here. This book follows the four Clans as they recover from the Great War, renaming themselves in shame from their ancestors. When Starclan cats begin to fade away, it is up to four cats, one from each clan, to keep the clans from forgetting their warrior ancestors.
