Minos' group was here in this place to follow the first matches of the selection. Each of them had a high position within the army, and for this, at least at times, to be present at this event would be something necessary.
Minos, as a leader, may see something in these soldiers that piques his interest, something that may provide him with new ideas and a means of meeting future soldiers. There were always one or two people with interesting innate abilities, even among ordinary people like these soldiers.
In Minos' army, there were already several like that. There was one with an innate skill aimed at hand-to-hand combat, another with an ability focused on mental power, another that could sense fluctuations of the soul, and so on.
