Cinderfur

Cinderfur is a thin gray tom.

Into the Wild

 * He was an elder when Brokenstar was driven out and was a friend of Yellowfang. He helped her, his fellow ShadowClan cats, and a handful of ThunderClan cats, to drive out Brokenstar by helping give Brokenstar a surprise attack.

Fire and Ice

 * In this book, he isn't seen, but it is revealed that when Nightpelt becomes leader, Nightstar appoints Cinderfur as his deputy.

Forest of Secrets

 * Cinderfur continues to be Nightstar's deputy despite his old age. He appears when ThunderClan are trying to get to the Gathering and have to cross ShadowClan territory. Cinderfur is noted to be highly aggressive, and says to his leader to say the word and ShadowClan would rip their pelts off.

Rising Storm

 * He was one of the first cats to die from the disease carried into ShadowClan by rats.

A Dangerous Path

 * Cinderfur was mentioned in the beginning of the book, when Tigerstar was talking about how Nightstar died of the sickness, and Cinderfur, who was the deputy, died as well. Nightstar was sick and could not appoint another deputy so the Clan was left without any form of leadership and went into ruins.
