Picture by me.
Nettlekit of Thunderclan was named after her mother was poked by a nettle before she was born. She and her siblings, Amethystkit, Emeraldkit, and Scarkit, lived happy lives and were made into warriors. Nettlekit (now Nettleheart) was not a big fan of Thunderclan's current leader, Featherstar. Scarfur led a patrol to kill a group of rogues on territory. Bluefeather was the only cat who went with him. Cought with a bloody paw, and Bluefeather killed, Scarfur was exiled. Nettleheart, Amethyst-tail, and Emeraldfall went with him, collecting rogues and clan cats to join four new clans. Branching off from the others, Nettleheart settled in the mountains, with Nightwhisker and her brother Darkshadow, Scratchclaw, Thornpaw, and others creating Mountainclan. She and Scratchclaw had Blackheart, Cloudstripe, Ivyseed, Spicykit, Wrenkit, and Spikekit. Nettleheart was exploring the new territory when she saw a willow on the moor. When she stepped closer she found Dawnfur and her parents, who joined the clan. Seeing Darkshadow, Dawnfur knew he would be trouble. Then, Darkshadow killed Blackheart, leaving Nettlestar in a pool of devastation. Darkshadow was then exiled. Darkshadow furthermore killed others, including the newly warrior-turned queen, Thornbush. Suddenly, Darkshadow died, leaving the clans safe.
