Separate from the other unnamed billions who walk the earth, each of these little groups of three or five or twelve, brought together by the shuffle of chance, then welded by blood, sees in itself the whole of earth, or all that matters of it. What happens to one of the three or five or twelve will happen to them all. Whatever grief or triumph may touch any one will touch every one, as they are carried forward into the unknowable under the brilliant, terrifying sun which nourishes all.
