Garethor, Torin, Zarvox - these three names represented the Death Knight, the Necromancer, and the Ghoul respectively. They were former subordinates of the previous undead lord, and Alex was well aware of their existence.
Alex wasn't surprised to see Garethor. He was the highest-level being in the city, so it was only natural that he would be the first to sense her return.
Alex accepted Garethor's pledge of allegiance. The moment she did, Garethor regained his status as a race king, his level cap rising from Sovereign level back to Divine.
Both Garethor and Torin had contributed significantly to the undead empire, and Alex intended to reward them accordingly.
"Thank you for your grace, Queen."
Garethor expressed his gratitude once more. His appearance was indistinguishable from that of a normal human. Although undead, his state of being, like Alex and Xiao Hui, was that of a living person.
