Clan Alliegences

Many seasons in the future, Thunderclan, Skyclan, Shadowclan, Riverclan, and Windclan are mere legends told by elders, long since abandoned when the twolegs came to bring the cats away to a much safer and cushy life. In their place, came three new clans -- Wolfclan, Badgerclan, and Cloudclan.
A kittypet named Heaven, descendant of Crowfeather, and her kit Celestial, leave the safety of the twoleg nests, to seek the dangerous lifestyle of Clan cats.

Shortly after their arrival to the Clans, things take a turn for the worse, and a new danger rises, forcing the three Clans to unite together, and face the truth they've denied for moons.
