In-between TPB & TNP
1.
When reconstructing Skyclan, Gorseflower had to preform what were essentially physicals on the incoming cats to make sure they weren't neutered/spayed.
It was odd, but she had to find out if the clan could sustain itself population wise. It was also to make sure they were healthy enough to survive in the wild.
She unfortunately had to teach Echosong how to do it.
2.
Leafstar named her daughter, Firefern, after Firestar while another queen, Mottlemouse, named one of her kits after Gorseflower. Her name is Gorsedapple.
3.
Whitestorm retired about a year into being deputy as his hearing started to go. Firestar named Longtail his successor.
4.
The group that rebuilt Skyclan was Firestar, Gorseflower, Elkeye, and Horizonstorm.
This is because I think it's unrealistic to have two cats completely reinstate an entire clan. Besides, safety in numbers.
5.
Longtail actually stayed a warrior for a long time after his injury, but retired with Mousefur and her mate, Copperfrost.
