Once everyone was dead, they looted and destroyed the spaceship as well. They even traveled through the asteroid belt to search for three secret vaults, which they looted, of course.
Michael had swallowed Memory Orbs en masse, providing him the memories to find the vaults and procure a wide variety of useful information. Michael retrieved the Needle of Lost Memories, removing the strands of memories he wouldn't need. Some memories of the Dark Heavens members were grotesque, similar to the memories of the Kitsun, and Michael was unwilling to keep them in his mind.
Since he had an item to remove the memories he didn't want to keep, Michael made full use of that function.
The Memory Orbs helped him find the location of a few smaller outposts and news of other traitor organizations who were either subordinate to Dark Heavens or connected to them through various strings. The memories were detailed enough to get moving right away.
