The official(?) Wiki for a completely normal D&D 5e campaign.
Use the navigation tree on the left hand side to explore the many facets of your adventure.
There's Ridholme, where your adventure truly begins. In there is the Manor itself, and some curious characters like Jared and Wonsten.
Learn more about the history of these lands, or perhaps the strangeness that is the Wyrd, including the sickness it brings, and the rare gifts it may bestow.
There are other places too, like Vale, and its foremost Agency - where you're employed - Blain and Forkuth.
