Play the Monster of Their Nightmares...
For centuries, noble heroes have banded together in the name of light and all that is good. They hunt what they do not understand – the cryptids, the supernatural, and other creatures of folklore. The monsters of every old tale.
In other words, they hunt you.
You are a daemon, what remains of the shadow, and you must survive these adventuring parties that wish to earn coin and renown through your extinction.
