Editing The Dark Woods (section)

=== Necromancers ===
At least one of your PCs is completely obsessed with mastering the darkest arts, willing to take on any rival power to demonstrate his/her/it's supremacy.  The other PCs either share his interests or accommodate him out of fear of what he might do if angered.

Whenever your PCs encounter ghouls or wraiths, you can choose to fight them as normal, or instead have the ghouls or wraiths immediately attack the other team.
