Ah! Accidentally deleted the question post below. You need either Jade Dragon or Horse Lords for this to work. I have no idea if it will function without one of these.

Updated! Apologies if this causes problems with saves or your campaign goals

Thanks! I'll take a look at these and see about implementing them with some localisation improvements in a few days.

There were also Norse trading outposts in Killiniq and Amadjuak, although they didn't seem to have much archaeological evidence of trade with people much further south. They were probably used for lumber camps and walrus hunting, although Norse artifacts have also been found among native Dorset sites there

Great work! I have a few suggestions if you want to make it a bit more historical.

Androscoggin in the map was said to have been a major trading site and a Norse coin was discovered by archaeologists there, said to have been from trade.

Agvituk was one of the historical endpoints for Native trade in the area, with trade goods from much further south being discovered in the area.

Several places on the map were also home to indigenous copper mining for trade with Mississippian towns and cities. These include Maqtukwek, Missisquoi, and Agvituk.

Ian Barnes's Historical Atlas of Native Americans also shows Native trade routes passing from Etchemins down to Aroostok and Wolystoq as well as Etchemins down to Androscoggin.
