Michael had quite a number of human undead.
And no, it wasn't as though he'd gone on a killing spree.
For one, he couldn't have done so in Aurora. There were far too many people more powerful than him there.
And while it was possible in the Land of Origin, provided he planned it well, Michael wasn't a killer by nature.
Most of these corpses came from the unfortunate souls the Hunters Guild had offered him as part of various tasks—bandits, fugitives, and the like.
Not all of them had been good people.
In one way or another, they all had blood on their hands. And Michael, someone who now operated in ways that might earn a frown from others, was willing to do what needed to be done—so long as it didn't cross the lines he refused to break.
This was how he'd acquired his human undead.
All of them were high humans.
The fact he could summon them proved it—Most times Michael never bothered to evolve an undead if he couldn't at least summon it first.
