But for Brymstone, I think you would have to start thinking more about the kind of society exists in that part of Thuland. It's described in canon materials as an early form of feudal society. Certainly some form of manorialism would have to exist and you would need to have villages, hamlets and freeholders in pretty large numbers to support a town of more than a few thousand.
Beltayne, Brymstone and Katorheim are the only three settlements on the canon map of Thuland, from which I've inferred their economic importance to Thuland. As the most southerly of the three, Brymstone is probably an important trade centre for goods to/from Clyster, Meore, Breylak, and Ongus (and farther). A permanent population of about 6,000 could perhaps relatively easily be supported by farming and fishing from the farmsteads that have claimed the fertile soils along eastern Ellesland and the fecund schools of fish in the Mergeld Sea, but the high transitive population of sailors, merchants, pilgrims, etc., makes this infrastructure creak - the PCs may find that they are subject to an undercurrent of discrimination by the locals, who resent the impact of these itinerants on their town. They may find prices higher, portions smaller, sleeping quarters more cramped, and so on. They may even find that local law enforcement overlook petty crimes against them, but come down harshly on crimes (or perceived crimes) they commit, etc.
Returning to real-world parallels, both England and Scotland exported wool, which could easily be mirrored between Albion and Thuland - there could be a lot of competition for the wool markets of mainland Legend, and a lot of piracy in the Mergeld Sea as each side attempts to sabotage each other's shipments. Possibly an adventure idea for a wider Thuland sourcebook than a Brymstone one (ships are being sunk - Albion and Thuland blame each other and tensions are rising, but actually the ships are being sunk by a sea monster: can the PCs figure out what's going on, find a way to placate the God of the Sea who's sending the serpent, and prevent war?)
