One of the professions that Rankers, and even Saints, didn't want to see in wars where each side numbered in the tens of thousands, was not a Sorcerer or a Wizard who could cast High-Ranking Spells that could decimate entire armies.
No. Each Kingdom had their own powerful mages that could do these things and more.
The profession that they were afraid to face off the most was none other than a Necromancer.
Especially Necromancers that didn't care whether they were killing friends or foes. In the end, it didn't matter to them. The only thing that they trusted was the Undead, and the more people that died, the more advantageous the battle was to them.
Necromancers that had become High-Rankers were true menaces to fight.
Saint-Ranked Necromancers were walking Calamities.
They specialized in curses, diseases, and other otherworldly spells that made even their fellow Saints didn't want to mess with them in large-scales wars unless it was a last resort.
