Death Knights, that's what the merchant called them. Beings with immeasurable strength who have been brought forth from the dead, their presence induced fear in everyone that beheld them.
Looking at the eyes of the Death Knight, Simon could tell that they were brutal warriors created with only one purpose. It would only take a single command for them to tear him apart immediately.
In this special area where he cannot muster any mana, he wouldn't even last a second against them. Even if he fought them at his peak condition, against opponents like the Death Kngihts his only victory would be in running. They weren't beings he could take on at his current level.
Simon had to admit, if it was Grimvul who raised them from the dead, than this merchant was a true master of Necromancy. His powers might be similar or even equal to one of the twelve heroes from Laplace.
