Happy St. Patrick’s Day

I hope this will be more useful than the Merry X-Mas Subsector.
I do think that this almost follow the rules for popular subsectors from a previous post. We have some backwater worlds, but they are not independent. We have 2 interstellar states. We have obvious adventures, and also a place called home. Dublin for some of us, Armagh for Eamon, and maybe somewhere else for someone.
The obvious adventures can be taken from the news (old and new) about Ireland.
This leads me to my suggestion of 4 races in this subsector. They should represent the Celtic, the Norse, the Protestants and the Catholics (or Old and New English). The lazy could use Humaniti, Vargr, Aslan and Bwaps or any other Traveller races that might fit. The more ambitious may want to invent their own races. An interesting scenario would be if the Humans represent the Celts. Then this will be in the far far future, when Humaniti have been driven away from their home-worlds to this cluster at the edge of the galaxy. Another interesting scenario could be if the Humans are the latest (New English) invaders. Then there might be some interesting moral dilemmas about the genocide of the original inhabitants of this cluster.
One thing to note about the map is that the towns and villages that are not in the map are still there as secondary populated worlds. E.g. Banbridge is a planet in the Armagh System. In the empty systems within the borders, there might be deep space objects.
