Somewhat unrelated, but
I really wish we had more follow up on the vampire spawn. While this setting isn't directly based on any real life country/time period to an extent where such numbers are faithful, most raiding Viking armies held between 1000-2000 men. A sizeable Viking force was considered to be around 3000 men.

Those are 7000 spawn. Sometimes I wonder if the only humane choice unleashed a greater evil on the world. Small settlements like the Myconids we meet stand no chance.
