After a week of observing the surroundings of the crater that the group of aliens had started working on earlier, they had finished their mission there.
Unlike Minos' group's mission, which was very difficult to carry out and which many of the Armhands had failed in the past, this group's mission was simpler. They weren't there to take something shocking that would even influence the lives of Supreme beings.
Their goal was to take advantage of The Obsidian Shore's opportunities and then take the corpse and belongings of that ox-horned being.
Minos paid attention to everything and kept what had happened in mind, eager to leave this place and show his superiors what had happened. Through his mental technique, Infinite Dream, doing so would be easy.
