Publisher's blurb:
Summon/Bind is a Lovecraft and Cthulhu Mythos horror scenario set in the modern day and is intended to be easily adapted to any Cthulhu Mythos inspired rule system.
Someone is executing a campaign of terror against the player characters. It starts out slowly and almost harmlessly. It escalates. First, only in intensity. Then brutally. Then worse, far worse... evidence appears. Immediately after, the demands start.
The players must cease the initiative, turn the tables, and track down their tormentor.
