The highest mountain lay somewhere to the east, tall, proud and mighty. It would withstand even the mightiest explosion that mankind sought to produce, whether it be pollution, malnutrition, deforestation, or a nuclear war.
David and Natalya, the only two known survivors, headed somewhere east. Even in their lone island, they had a sort of hope that they both contributed to the invisible pot between them. They meant to share their food for survival with any other they found alive.
They both knew, deep inside, that the same catalyst that had so nearly destroyed their lives had also nearly destroyed their chances at survival, what with the complications of a beautiful rose. When nature was pushed too far to the brink of extinction, an all-out nuclear war had manifested to knock a bit of sense into people, the inhabitants of nature who so blatantly destroyed it.
Technology, a common product of mankind, had been too much for the world to handle, so a higher being decided to give a second chance, with fit and knowledgeable characters, to be able to unite every island with a common thread: an affinity for nature.
This time, mankind knew better. They would not push so ruthlessly against the wind while at sea, and instead let it guide them through an adventure to a world that could then be envisioned, truly and really, as home.
