So there you have it, the basic fluff for Cadoren. More info coming soon, but for now, a few places of interest (though by no means a comprehensive list).
The Cerulean Gaol (01.19)
Prison-Tomb of Korrin Landwaster (14.04)
Korrin's Curse (16.08 and surrounding hexes)
Jorl's Eyrie (06.19)
The Fishing Village of Dwyn (08.12)
These and others will be detailed as time goes on. Eventually, I'd like to collect all the info on Cadoren, and the rest of the world if I ever create it, into a setting atlas.
