The Korblox Necromancer

The Korblox Empire, even if weakened by the Overseers, still had their magical forces at their full integrity, and they participated in this war even if under the covers. They threw blessings at each Phantom soldier that fought against the Overseers, but even with that, it wasn't enough to destroy the empire. Seeing that their blessings and curses didn't alter the outcomes, the Korbloxes took advantage of how distracted the Overlord was and invaded the Overseer castles, where they stole treasures and turned the Overseer Soldiers into Korblox Deathspeakers, that way without raising suspicions, they were able to regain their strenght and become even more dangerous than they were before their defeat.
And now... if the Overseers were to be destroyed... Robloxia would be in even worse trouble then they already were.
