So now I've got all the chargen rules for my Carcosa game sorted, I've started having a bit of a think about an initial adventure, and whereabouts on the large campaign map it'd be set. The obvious place (I thought) is in the vicinity of hex 2005, as that has already been described in greater detail in the Fungoid Gardens of the Bone Sorcerer adventure. So I chose hex 1905, one hex to the north-west of 2005, as the starting point.
To get things going, and to kind of orient myself in the setting I've created a basic map of hex 1905 and the six surrounding hexes. For now it just shows the points of interest which are described in the Carcosa book, with some names I've made up and a road drawn in between a few of the settlements. Seems like a good start... I'll add more details as I go.
