question:  Which was probably the biggest motivator for Melia to volunteer?
context: ] I was wandering among the tall grass of the slopes, listening to the soft whistling of the wind; allowing the grass to caress my toga and thighs. But I knew that where Xeon is, Melia must soon appear. And indeed it was but a moment before Melia slipped through the high grass to stand at his side. Melia was a She, with the swelling breasts that were, so tradition states, quite prevalent among members of the race long ago, and are seldom seen today. Indeed, Melia was on this account made the butt of many jokes and, I fear, would have had a lonely life of it had it not been for the friendship of Xeon. "Sias," they were saying, "the Maternite's gone." Everything has evaporated in Maternite. "There is nothing left," Melia insisted. A man my age does not hurry in the heat of the midday sun—maddugs nenglishmin go out in the midday sun, as the ancients say, although I often wonder why—but Xeon and Melia ran all the way down to the city. Xeon and Melia stopped as I mounted the steps, but I smiled and motioned them in. At such a time, many men feel impelled to make speeches, and one must not be disrespectful. Prayers and supplications were offered to the gods, priests were sent to sacrifice, and finally, as the light of the sun was falling between the pillars, the High Priest of the Maternite Machine was heard. Yet perhaps it is for the best, for those left were the most earnest and intelligent. Know, then, that once granted a few cells of Prelife, it is an easy matter for the Maternite Machine to add more and more; thus assuring us, as has always been, a continuous source of Prelife to be born by the Generating Machine as children. The machines bear the exact number of children each year to balance the number of us whom the gods claim.
