Helmut Halfsword - killed within Willowby Hall
Undead knight of the crescent moon order (12th knight).
His Sarcophagus was in the museum on the top floor of Willowby Hall.
He was reawakened by broken seals in the entrance hall of the manor.
He said he only obeyed his master, Elias Fenwick.
When the Bell of Tom the giant hit the Wall near the Death Knight, it shouted in pain, "NOT THE BELL OF ST.CUTHBERT."
Reanimated the dead Zapler to fight for him.
He killed Helmut Halfsword and trapped Grisha Goldstein in a bone cage.
With everyone fleeing Willowby Hall, it seems the Death Knight is currently in control of the manor.
