When he first saw the old man, Sesame Rice Ball nearly started a fight.
An Undead!
The old man was incredibly skinny and a dark glow pulsated in both of his eyes; he was clearly an Undead.
The Undead mentioned here weren’t the same as the Undead who had been affected by the Plague and didn’t have their own conscious. The Undead here had their own consciousness; they followed the lead of Queen Sylvanas and referred to themselves as the ‘Forgotten Ones’.
"Who are you all? Why are you wandering around in the kingdom of the dead?" the old man asked with his hoarse voice. He spoke in the common tongue, a language that suited all races.
Sesame Rice Balls only came to notice that the old Undead was radiating a faint yellow glow that was almost unnoticeable. This meant that he was neutral, unlike the other Undead who were hostile units.
