Even if the Supreme Human Alliance had yet to reach mankind with their disturbing view of other races, Michael could imagine various Supreme Families, Great Clans, and High Nobles joining their mission. Maybe, they would do so secretly once Hyumans found a way to travel to the solar system, or the Lumina Stellar System, but their mindset would change quickly once they realized how wealthy Hyumans and the Supreme Human Alliance were.
Michael didn't hear a lot but reading Mihal's mind was enough to understand that the Supreme Human Alliance was currently solely relying on their pocket change to support Dark Heavens and other shady organizations. Yet, this pocket change was more than most Supreme Families and High Nobles earned in decades.
It was enough to nourish hundreds of Higher Lifeforms and to use them as sacrificial lambs whenever the need arose.
