We All Shiver

Prologue
"There are two types of strong." two cats sat next to each other on the edge of a river. Mist floated about them, making it hard to see what they looked like.

"And these two types of strong will rise to save their clans." the second cat meowed.

"But they may battle, for they do not get along."

"They may, but it does not matter."

"Power."

"Kindness."

"But both have their limits. Will they survive?"

"Only time can tell." the second cat sighed. "Eventually, the cold will be terrible enough that the strongest will shiver."
