ShadowClan is a group of cats living in the marshlands. They have always seemed to be the darker clan due to the evil leaders in the past but is now regaining it's trust among the other three clans. Their cats are known for their silent hunting at night and their main prey are amphibians and reptiles.
"Few are welcome here, in our world of secrets and darkness. We are a Clan of cunning and cleverness, a Clan well suited to the shadows of the cold north wind. No other Clan can walk the paths of night like we do. Other Clans may be faster or stronger, but we are the most dangerous warriors: fierce, proud, and independent. We are ruthlessly willing to do what it takes to protect our great Clan. There won't be any softhearted alliances here! ShadowClan will always be the dark heart of the forest."
