EarthClanners are tolerant, compassionate, and grounded.  The Warrior Code is generally considered to be a good general outline on how to live a good life, but is rarely implemented to the letter and EarthClan values encouraging each cat’s strengths rather than upholding the conformity of the other clans.  Of the clans, EarthClan is the most accepting of outsiders and has the most variable belief in StarClan, with both devout believers in StarClan and the most skeptical cats living in harmony.  While EarthClanners are expected to work with and protect their clanmates when necessary, cats are usually closest to their immediate family and a small group of friends.

EarthClan has the most flexible idea of what a clan is and what the role of every cat should be, which is reflected in the clan’s hierarchy.  The leader typically take a gentle approach to leadership, opting to guide their clan through times of hardship and counseling members through disputes, rather than demanding total loyalty and obedience.  The deputy has much of the same authority of the leader and is usually expected to support the leader with the administrative tasks of clan-life.  The role of the medicine cat is extremely variable, as each medicine cat is allowed to find their own balance between their roles and healers and spiritual guides for the clan.  Often the medicine cats act as confidants for the warriors, and thus works more closely with the leader in determining clan policies than medicine cats in other clans typically do.  Warriors protect and feed the clan, but the relative lack of dangers and abundance of prey gives EarthClanners more leisure time than cats of the other clans.  Much of this time goes toward building strong ties with their other clan mates by exchanging apprentices or sharing tongues.  Apprentices, meanwhile, are encouraged to see their mentor as someone who can help them on the path of refining their own unique talents, rather than someone responsible for teaching them the specifics of clan hunting and fighting techniques.  Training sessions are therefore centered on what the apprentice’s specific talents are, and mentors frequently call in other warriors who complement the apprentice’s growing talents to help.  As a result of this individualistic approach to training, EarthClan has no overarching battle strategy or known fighting techniques, which makes them an unpredictable enemy.  Kits are cherished and protected by the clan, and given a bit more room to cause trouble than the kits of the other clans are.  Elders are held in the highest respect, both honored for their wisdom and their many hard seasons spent serving the clan.  They give advice to anyone who asks- and often those who don’t- and are expected to teach kits about StarClan and the Code.

EarthClanners are content, well-fed cats with bright fur of many colors.  Their pelts tend to be longer than those of cats of other clans, which makes them an asset while swimming.  Due to this and the rare appearance of scars on their pelts, EarthClan cats are often considered to be more beautiful than cats of the other clans.  This has two effects: the high occurrence of cross-clan relationships involving EarthClanners, and that EarthClan cats have been be kidnapped by twolegs who mistook them for lost kittypets.  Somewhat to the bewilderment of other clans, many EarthClan cats have a talent for swimming and are even known to splash through the muddy rivers just for the fun of it.  The wide variety of talents that EarthClan opts to nurture results in a diverse set of hunting strategies, making them collectively capable of catching any type of prey they may happen upon from rodents, to birds and even to fish.  As a result of this wide variety of hunting strategies and the sheer abundance of easily caught prey, EarthClanners are by far the most well-fed clan and have more leisure time than the other clans.

However, their lives are not without danger.  While foxes and badgers are rarely found in EarthClan’s territory, venomous snakes have claimed the lives of many EarthClan apprentices and cats must always be on the lookout for them when wading through the marshy forest.  Fish serve as the primary prey for EarthClan warriors, though they are known to hunt land creatures as well.  Birds are seen as a last-resort and many cats turn their noses to them outside of leaf-bare. EarthClan is the most well-fed clan, however even they are affected by seasonal drops in available prey.  While they are rarely in danger of starvation, Leaf-Bare ends their time of plenty and more frequent hunting patrols are sent out.  New-Leaf is the most dangerous time of year for this clan, as increased rainfall can lead to flooding.

EarthClan’s marshy forest territory is tied together by a net of rivers that both provide prey and offer a natural barrier against the other water-hating clans.  The forest is thinner than that of MoonClan and is known to flood during New-Leaf, but is rich with a variety of prey.  EarthClan has a fittingly comfortable home, lying just below a fork in the river.  Just where the river splits, the medicine cats have made their den out of woven reeds.  In the center of the camp lies a large ivy-covered rock, where the leader performs ceremonies, with an old tree leaning against it.  Under the boulder, much like in MoonClan, lies the leader’s den.  The tree itself houses two dens, the elders’ den and the nursery, under its tangled net of roots.  Eastward facing is the nursery, kept a safe distance from the river.  The elders den is cozy, with a padding of warm moss.  It lies under the same tree as the nursery, facing westward.   The warriors’ den lies in a thorn bush right beside the river and is known to flood in bad weather.   The apprentice den rests under a dense bramble thicket, across the clan entrance from the warriors den. An old fox den served as the prison during Sharkstar's rule of BoneClan, but it has since been destroyed and converted into a shallow pool for kits to safely play in.  The river marks their border with MoonClan and SunClan to their north and west, and to the south and east thunderpaths mark their borders with the Loners Forest.   Hawk’s Tree lies in the northwestern point of their territory.

EarthClan was formed by two unlikely allies: fierce and cunning NightClan and kind and peaceful DawnClan.  While this merge was initially rocky and the other clans refused to acknowledge their legitimacy as one, new clan rather than an alliance of two clans, EarthClan settled into their identity and territory after a generation.  This unique history is the cause of their belief that tolerance and acceptance of individuality, rather than conformity, should be among the foundational pillars of a clan.
