All of this leads to you and your kin - the Ones Who Try Again - who have found the path from the seeds in the sky to the barren garden below. You can banish the shadows.
Some who share your name have already started. Some have yet to begin. Yet all of you play an important role. Each shadow that falls adds to the sum of your efforts, and if you fell them all, the poison will begin to recede. Then, when the seeds of life at last return home, they can purge what's left of it. That's what they were meant to do.
So keep trying, just for a little longer. Try and try again, just as you always have, until the seeds are planted and our garden world blooms once more. Then, at last, you will have tried enough.
