Without knowing exactly since when, the group was running so fast that those with the weakest endurance were beginning to pant loudly. Those whose the Aether stats were below 40 before the Ordeal automatically had their stats raised to the Ordeal's Aether density, which was the best gift the Oracle could give them in terms of fairness. If they still couldn't keep up, this Ordeal just wasn't for them.
The first Ordeal had the decency to give different tasks to different people, because each person's starting point was different. However, even the "non-physical" Ordeals required a minimum amount of physical activity, ensuring that each Player was at least able to run decently at the end of it.
Just as children were entitled to a first special extended Ordeal to accelerate their growth and maturity, obese, elderly or physically impaired people followed their own course and the special rewards offered ensured that their physique met the standards required for the second Ordeal.
A few digressions:
-The system numbers are obviously simplified for ease of reading. As the Oraclean uses other symbols and all kinds of sounds and phonemes, the alphabet used and the numbers are in principle different.
-The Black Hole Era is a real term and our Universe will spend 99.999% of its life in this form. In other words, in complete darkness.
-A normal human being, if not exposed to direct sunlight, can last up to 90 seconds naked in space and loses consciousness after about 15 seconds. Do not hold your breath, as the dilation of oxygen would make your lungs swell.
