Corkirk: Demons of the Mist
Corkirk is a small village built over the foundations of a much older settlement. When the neighboring settlements begin to fall to fire and ash with no survivors, the people of Corkirk look to members of the community to stand up and become heroes, to find out what has happened to the other villages and prevent Corkirk from suffering the same fate.
This is a D&D 5E campaign starting at level one. It takes place in a custom setting with a dark ages level of technological development.
