Basically it went something like this.
- I created a starting area on the map.
- I asked people to provide a description of any of the adjoining rooms.
- I selected a few of those ideas (combining several suggestions whenever possible).
- I drew in the new areas, and posted a picture of the updated map.
- I then repeated the process for the new rooms...
So, if you want to download a pdf copy of this map (along with all the descriptions) you can find it on google drive HERE.
And if you want an unlabelled copy of the map (for use with a VTT for example), you can find it HERE.
Anyway, here's hoping you'll be able to get some use out of it!
