Clans of the North Prologue

Many moons north of the four Lake Clans, you will find the Clans of the North. These Clans live in conditions most cats only have nightmares about. Six moons of the year contain nothing but snow and sleet and cold that settles deep into the bones of the wary. These cats, however, have long learned to live in such conditions. Their bodies are stronger and their fur thicker.
The Clans are as follows - Ice, Snow, Cold, and Frost.
IceClan is the furthest to the north. It is truly the coldest Clan, experiencing larger snowfalls and lesser prey than the other four clans. It's territory is larger, but also less disputed.
SnowClan is to the east. SnowClan cats are known for their special paws that help keep them from sinking into the snow and to help them stalk prey much more silently.
ColdClan is to the west, experiencing considerably less snow. However, they suffer from little shelter and high winds, and many a kit have died from sheer cold in ColdClan.
Finally, Frostclan from the south. Their territory is the smallest and yet the most bountiful, for it receives little snow and is the warmest of the four. It experiences only five moons of leafbare.

The four Clans have lived in relative peace for many moons now. There have been skirmishes and battles. However, from the snow and cold and wind will rise two ambitious young cats and a new prophet will be born. Secrets will surface and darkness will rise. Our heroes will fight it - but will they succeed?
