If you're right and judging from the bones, it's obviously the evil work of Bonedeep Assassin Carlo. Wagner falls deep in thought.
The fool must've been bought by the Black Blood Alliance! We should find a way to take out Carlo before he kills more people.
%n%, please take this fake knight seal to Auris Bay and disguise yourself as a surviving Elsaland Knight to draw Carlo out and kill him.
Time for him to pay for a lifetime of crime.
