The original four Clans are dead. Once again, Twolegs have invaded their territory and destroyed the Lakelands. As the four Clans watch in distress, Emberstar of ShadowClan suggests the unthinkable: to split themselves up.

As the stars twinkled in agreement, the message of their ancestors could not have been more clear...

Unite...
...or die.

Now there are five new Clans, each made up of half of one of the four Clans and half of another:

MarshClan, the ShadowClan-RiverClan mix of cunning and intelligence.

TreeClan, the ThunderClan-ShadowClan combination of courage and wit.

SandClan, the RiverClan-ThunderClan alliance of agileness and audaciousness.

BarelyClan, the WindClan-RiverClan joining of loyalty and brawn.

SunClan, the ThunderClan-WindClan union of skillfulness and swiftness.
