Ambergris – The Eonir offer good prices for ambergris, with a pound of good quality ambergris able to buy a bottle of good quality elven wine. In addition to being used in perfume the elves of Laurelorn also use it as a component of incense, as a spice and, if rumors can be believed, for more arcane purposes.
Chocolate – Bought in very small quantities for very good prices. A luxury with only a handful of buyers, chocolate is even more exotic to the Eonir than it is for Imperials. Demand is increasing ever so slightly as the years go by, presumably due to more nobles being introduced to the delicacy.
Gemstones – Naturally command high prices. With the exception of amber and, to a lesser extent, pearls the Eonir seem to have few sources for gemstones of their own and those that they do have are rather limited in output. They are used for ornamentation and jewelry of course but are also said to be valued by the enchanters among the elves. While the best prices can be obtained from the Dwarf holds in the World's Edge Mountains, the dwarfs tend to keep the finest specimens for their own kind. As such one should not discount those mines operated by humans as a supplier.
Ivory – Bought in modest amounts. Used for ornamentation, naturally, and also for the crafting of magical items. For the latter purpose ivory can (supposedly) be divided into two categories; Ivory from land dwelling beasts such as elephants, sabretusks, mournfangs, etc. is said to contain
Ghur, while Ivory from creatures of the sea such as walruses, narwhals and such supposedly absorbed
Ghyran from the ocean. Either way the Eonir will pay good prices for it. Sourcing is the latter variety can be somewhat difficult, becoming exceptionally so if one is unwilling to deal with Norscans.
Livestock – Sold for use as sacrifices. The overwhelming number of livestock purchased are sacrificed shortly after being purchased. Cattle are preferred, a custom I have been told dates to when the ancestors of the Eonir lived on Ulthuan.
Olive oil – A luxury product purchased only on occasion by the wealthy, as the Eonir generally prefer to cook with fat. Still when they do buy olive oil the prices are very good. They expect only high-quality olive oil, as such one should generally attempt to source it from Tilea as a great many of Estalia's best groves were destroyed in the Chaos invasion.
Ores – Ores in general command good prices from the Eonir as they appear to have few mines of their own. Prices of course vary depending on the type and quality of the ore.
Ostka – Surprising I know, but the Eonir buy small amounts of ostka, supposedly for alchemical purposes. As such their expectations of quality are minimal, if it's strong and it won't blind you, they'll buy it.
Salt – Bought in good quantities for good prices. Only rock salt is purchased as the Eonir can harvest sea salt from their own coastlines. Eonir merchants expect only high-quality salt, and woe to be to any merchant that tries to cheat them. I still have nightmares about what happened to Reinhilde. So many mushrooms…
Specie – If one has nothing else to offer the Eonir are willing to accept specie as payment, though they prefer to trade via barter. Nonetheless specie will fetch good prices from the Eonir, though not as good as from the dwarfs.
Spermaceti – To the best of my knowledge this is bought by a single individual, a rather old elf who was one of those that colonized the Old World during Ulthuan's golden age. During the time before the War of Vengeance this individual was a chandler who knew the secret of creating spermaceti candles. With the Eonir trading with the outside world they've decided to restart their old trade and has earned a solid reputation for manufacturing the finest candles that can be found between Ulthuan and the World's Edge Mountains. The prices they offer for their raw material is quite good and the quantity measured in hundreds of pounds per year.
Spices – Nordland merchants appear to have a near total monopoly on spices from the Far East such as pepper, cinnamon, mace, nutmeg, and cloves. Bought only by the wealthy. Naturally we're able to obtain extremely good prices, for example three pounds of cloves can buy a barrel of some of the finest wine the Eonir are willing to sell. Amount sold is steadily treading downward after the initial buying spree. I suppose they've decided that the prices demanded in exchange for them are simply not worth it, though Hans has a wild theory that the elves can get the taste of spices from common herbs and flowers like honeysuckle and dried hawthorns.
Troll blood – Supposedly a common reagent used for a great many purposes. Prices are good due to the difficulty of obtaining any whilst keeping all of one's limbs. Transportation in somewhat difficult of course as the blood has to be rather fresh for it to be of use. Try to obtain it from villagers and minor lords who are happy to simply be rid of the troll rather than getting into a bidding war with dwarfs in Wulfenburg
Unworked and semi-worked metal – The Eonir purchase not inconsiderable amounts of unworked and semi-worked metal, whether it takes the form of ingots, manillas, rods, bars and so on and so forth. From what I can gather almost all of this is used for mundane purposes, such as nails and pots, ordinary arrowheads, fire pokers and spades, etc. Nonetheless quality is expected to be high, any merchant trying to pass pig iron or such on them can expect to be blacklisted.
Vinegar – Bought in only modest quantities. Quality is not expected by the Eonir, if they wanted that they would trade among their own kind. Said to be used primarily for industrial and alchemical purposes.
Vitriol – Blue, green, and white are all bought in small quantities for good prices. Used in alchemy. Obtaining vitriol is somewhat difficult due to the control the Gold College has over the market for it.
Whalebone – Niche good, used primarily for crafting enchanted bows. Whalebone supposedly contains not inconsiderable amounts of
Ghyran. Prices are good, better than what can normally be obtained from tailors and the like. Demand is much too small to be relied upon however. Problems can occasionally arise during trading as well, as discussed below.
Whale oil – Niche good, bought only on occasion and in rather small quantities but the Eonir will pay good prices for it. Said to be used for quenching blades. Best sourced from Norscans via Marienburg. The elves will occasionally refuse batches of whale oil on the grounds that "the hunt was unfair" or of "unnecessary cruelty to the beast" and no I do not understand why. For example, six years ago Svetopolk Lushash offered them thirty-eight barrels of good quality right whale oil for exceedingly good prices. Rather than buying it the elves grew stern and even the dullest merchants could tell that they were simmering with barely controlled anger. Never before had I seen the Eonir become so alien in aspect and near all merchants including myself left within the hour for fear of our lives. And though that was by far the worst of such reactions, it wasn't the only example of one.
