Adding to Sons of Anarchy (Sons of Anarchy Supplement)
From D&D Wiki
If you are inclined to add creatively to Sons of Anarchy please feel free to do so. Small towns within each territory could be added (in keeping with the theme and locals of the region is possible). New clubs and gangs can be added relatively easily. NPCs of reasonable appropriateness are always appreciated.
If you seek any assistance or have questions regarding the appropriateness of what you wish to add, just seek out User:Hooper, the Sons of Anarchy representative on the D&Dwiki and he'll gladly help out.
If you wish to try out some items or additions, use the Sons of Anarchy Sandbox.
