Herald Of Nod
This is the blade that was taken from the sacrificial attempt on the girl. Quovan, the guy from the Mutliverse thing, had been to the altar, intriguingly.
It seems to be an intelligent knife that claims to be the Herald of Nod.
The knife has generally been held only through a cloth intermediary. Lord knows that it’s likely a dangerous thing to hold bare-handed.
It had been in ‘use’ at least one time before. The freaky girl that we saved – the one that was about to be killed BY the Herald of Nod – took hold of it once and murdered a barracks full of Black Order troops.
