Several thousand years after the Third Pantheraseer's reign, the land has changed. Rising sea levels have swallowed entire continents, and, displaced by the water, cats have had to migrate to higher ground, causing unrest between the snow leopards of the mountains and their intruding African cousins. Such conflict over several centuries has changed the snow leopards. Weakened by war, they no longer know how to love each other. Even the strongest form of love - that of a mother for her child - had become severely damaged, to the point where love has been pronounced extinct. This is the Longest Fall. The cats have fallen so far out of their faith that they've forgotten their love for each other and for Panthera. If they continue to fall, they may never be saved. That is why it is time for a new Pantheraseer to rise and teach the cats how to love again. But at the same time, she, too, must also learn how to feel and welcome love's warmth.
