Nordland still has access to Laurelorn Lumber, which is about the highest grade lumber in the Old World outside of illegally harvested Athel Loren Lumber - the latter which is almost always painfully purchased with blood and death by furious Asrai/Forest Spirits. They still get exceedingly carefully monitored harvesting zones, which rotate and move about, while illegal harvesting attempts outside of said zones are still intensely and often fatally punished. It is an incredibly lucrative business, and is largely controlled by the Elector Count by way of licenses/permissions being purchased at high cost to operate in said zones, with exceedingly high legal fees if said licensees go outside permissible zones in any respect at all. The EC determines who gets to go in and harvest, which grants significant power over them. The selling of said lumber is subsequently of great worth for Nordland based traders, increasing overall economic prosperity for Nordland.
Nordland still has access to Laurelorn Animal Materials, rare and fine things indeed, which are considered exceedingly high-quality luxury goods. Whether it is the pelts of beavers, wolves, foxes, squirrels, hares, deer and so on, which all repeatedly prove to be exceptional examples of furs no matter what (unless falsely identified), or things like horns or teeth or various other items that alchemists/researchers/etc. might which to make use of in a multitude of ways, they cost a fair shilling but are generally considered worth it by those who get to make regular use of them. The Gold College and Jade College, for instance, purchase such materials for their uses through connections forged between Nordland and Laurelorn. Those looking to participate in such trade operations must pay regular fees to the office of the EC for the priviledge of doing so, while the trade itself improves overall economic prosperity for Nordland.
Nordland still has access to Laurelorn General Elven Goods, whether simple trinkets or more proper artisanal creations, purchased with coin or barter by way of livestock and such for uncertain purposes. The value of such things cannot be ignored, given that they are often acquired by Nordland traders who are then able to upsell the items elsewhere due to their exceptional quality and general exoticism. Which, in turn, improves overall economic prosperity for Nordland. Minor concoctions or potions are also of high value, even if only because 'its elfy which mean's it's got to work', which can and has been leverage for satisfactory profits.
Nordland still has issues with smugglers, but the activity of such things has been vastly reduced by the Eonir taking effective vigilant possession of their Laurelorn coastline. Smugglers now are forced to try and ply their trade directly in the main Nordland settlements where guards and trackers and those dedicated to the law are in high concentration. Wreckers have gone extinct along the Laurelorn coastline of the Sea of Claws, greatly improving the speed and safety of sea-based trade with Nordland heading in from elsewhere in the world, which directly increases trade income and overall economic prosperity for Nordland.
Nordland now has access to - and makes use of - Eonir Ghost Striders and others as trackers, hunters, etc. against threats to the province and the forest both i.e. beastmen, greenskins, bandits, skaven, mutant bands, those who start calling upon Dhar (Necromancers, large pockets of ghouls, devotees to the Dark Gods, witches who need to be either curtailed and sent south to the colleges or culled outright) and so on. Particularly pro-active Eonir i.e. younger ones - are even being utilized in carefully negotiated advance parties to help said activities between Stephan and Naraiel. Elven expertise aids in such things, while the Elves get to feel better about getting rid of threats before they have a chance to hit Laurelorn proper. Thus improving overall safety of the province, positive outlook on Eonir, reduces casualties for the State Troops and Militia, and various other knock-on effects which additionally culminates in increasing the overall economic prosperity for Nordland.
And sometimes, someone thinks they have a good plan, and will try to secretly insert a group of loggers or hunters into the forest, or a Witch Hunter will try to persecute the foul inhuman magically tainted magic users, or a particularly determined Taalite priest will just try and walk in to tell them that their Gods are wrong/dumb/bad/don't exist and that they should worship Taal.
And those people don't come out again.
So. You know.
