Fern
Fern was a she-cat that started out as a kittypet and joined the wrong crowd. When she left the twoleg place she met the RRG and in search for a family and companions she joined. This decision brought her happiness-- and her death. She gained friends, skills, self defense, and even a crush. But during her last battle with Horizonclan she changed her mind. She wanted to be clan cat. She left the RRG and joined the clan. Though shortly afterward she was killed by Carcus, because the RRG had discovered her plan to inform the clan of their secret weapon. The Otherclan.

Fleabag
The name had been more of a joke than anything, but strangely enough, Fleabag quickly grew into it once he retired to the Elder's Den. Fleas seemed to attack the poor white tom, relentlessly biting at his legs and rump, making him the worst elder to look after for poor apprentices. When he had been young, the arthritic cat had been the best hunter in the clan, but time and age unfortunately took away his skills. However, he relives those times constantly by telling cleaning apprentices stories of "the good ol' days." He may be a pain to take care of, with the amount of fleas and constant complaining, but being around the creaky elder is usually a reward for the stories he tells. Fleabag is the HorizonClan Keeper of Tales, ranging from his childhood to clan troubles to StarClan. Since there is no apparent Companion around the old tom, it is often joked that it's a persisting flea of no name.
NPC (all can use)

Moonglade and Ryza (Seagull)
Due to Moonglade's careless neglect, Ryza had her wings broken, and soon were torn off. That crushed Moonglade, and her spirit died. Being as foolish and careless as ever, she strolled on the Thunderpath, and was killed, an appropriate death, for a Clan cat that never really cared. Her shell cared, but her heart never had it, and she made up her warrior name. She was a rogue her entire life, but had a companion. Her rogue name was Star, but no warrior name started with Star, so she changed it to Moonglade. Sungazer was just in a fire, so his senses weren't corrected, and believed forever that she was in the Clan, and he didn't know it. Moonglade was a deceiving, ruthless cat, but no one knew.
Kei

Oakface and Geo (Chipmunk)
Ever since birth, Oakface had proved to be a lively and proud creature, always testing the boundaries of her freedom and the tolerance of others. However, as she grew into a warrior, the she-cat found a different excitement; providing guidance to others through mentoring and advice for problems. She lived for the rules and living by the Warrior Code, often disapproving to those who didn't. She has a special faith in StarClan, believing in them with all her heart. Though she's kindly and bright cat, she does have a bit of a temper to her, especially when loved ones are involved. Her greatest achievement to the clan, in her opinion, are the three perfect little kits she produced; Flamepaw, Pumpkinkit and Pinepaw. She has a unique beauty of tabby-coloured splotches on her back and face, seemingly paint splatters on white fur, but it's greyed over the years and her muzzle is now entirely voice of colour. Her eyes, magnetically friendly, are a yellowy green colour that seemed to smile constantly, even in her aged body. Like Oakface, her chipmunk Companion, Geo is a barrel full of energy and life, and often races around the HorizonClan camp for no apparent reason. Oakface has scolded him for disturbing the calm, but why would a wild chipmunk listen? Despite the seemingly lack of respect, the two love each other to pieces.
Swift

Timberdust
Timberdust has a puffy brown pelt that covers his apprentice-sized body. His yellow eyes are large, and stand out on his dark face. His legs are a dark brown, and his tail is long and silky. He was Clanborn, and his pelt is a mystery. He lost his mother, and his father was always unknown. He has done well at hiding his emotions of sadness and pain. Being a Medicine Cat, he needed to stay optimistic and raise cat's spirits.
Kei

Skystar and Taskein (River Otter)
Some would agree that this blue gray leader, with her storm gray and navy eyes, brought a new shine to HorizonClan's history. In a battle to the death, in the time where rogues and the ghostly FangClan, Skystar killed her enemy, the deputy Stone. Within that, she was killed herself and Stone in a death grasp.
