Cool! I'll tell you about a clan I made when I was younger.
It was called ForeverClan, and was the 6th clan. The leader, Forever Song, was a grey and white she-cat who had the abilities of the other clans (swift like Wind, strong like Thunder, quiet like Shadow, and swimming like River). But she had many downfalls.
The generation I started with was Lizardstar, an evil leader who came by a few leaders after ForeverSong. He was a immoral cat, and in the end, his own mate, Crismonheart, killed him to become leader. She was a good cat. However, she didn't realize that she had a kit with him (she had assumed they all had died), and that cat, Blizzardpelt, came back to torment her deputy, Icestorm, when he became leader. Icestorm's first deputy was his son Thunderbird, then Thunderbird got a mate (Mintheart), even though the clan medicine cat at the time (Dewshine, she was just an apprentice at this time ) was in love with him, and had some kits. Resulting from that was a character called Crowflame, who ended up with Shimmermoon(I know, the moon suffixes aren't allowed XD). Annnd then they had my last few characters, Brokensong, Fallenblossom, and Riverpaw (Riverpaw died because of Blizzardpelt, who was the main villain after Lizardstar).
Basically:
Lizardstar was before Firestar.
Icestorm (-star) was during Firestar.
Doeleap (-star) was after Firestar.
Hope you enjoyed this! It was rather dumbed down, since it was sooooo long. I developed the history for over 3 years.
