What happened after that?
The forest territories
After the battle, moons passed and nothing significant happened. Of course, there were border skirmishes, but not battles like the great one. After a long time since the founders of the Clans went to StarClan, Twolegs came to build a new Twolegplace in SkyClan territory, and there was no more places to hunt. SkyClan begged the other Clans to help, but the others told them to leave the forest. SkyClan left and found a gorge to live in, but soon rats attacked them, too many to count, and the Clan scattered and became kittypets or loners. After a long time, the heroic ThunderClan leader Firestar was sent to restore the lost Clan. He found the only living member of SkyClan, Sky. His mother's mother lived in the Clan. Firestar took advice from him and SkyClan was a Clan of warriors again.
SkyClan
Soon after, the forest Clans had to find new terriories, because the Twolegs were bulding a bigger Thunderpath for their monsters. The cats journeyed on the trail of the setting sun and found suitable territories for each Clan near a lake. The lake was near the Sun-drown-place (sea in human words), where the wise old badger, who played a significant role in the Clans' history, Midnight, lived.

Whatever happens, the warrior Clans will survive forever!
