Did I miss something?
Indeed, one should consult the sources prior to writing. So here some more lapsus:
Azadmere Kingdom Module AZADMERE 1, HISTORY: The city and kingdom of Azadmere were founded in 6894 BT, by Ahzrdin, leader of the Thazhain Khuzdul, and for six millenia
of the Codominium, only dwarves dwelt there. Some of the first Jarin to reach Harn were permitted to settle within the kingdom because they had a tradition of farming and
fishing, trades which the Khuzdul found distasteful. The relationship was successful and some Jarin refugees of the Atani Wars were also allowed to settle within the
kingdom. With their agricultural needs met largely by the Jarin, the Khuzdul were able to refine their own special skills, a division of labour which benefited both
Azadmere Kingdom Module AZADMERE 1, ECONOMICS: The Kingdom of Azadmere is the only district of Harn required to import food. The high altitude and poor soils do
not permit wheat to be grown; oats and barley are the staple crops. Wheat and other agricultural products are imported from Kaldor. [...]
Azadmere Kingdom Module AZADMERE3, 5. VILLAGE OF TANIZ: The residence of most "clanless" humans of the city. [...] The principal occupations of Tanizites are
labouring (in Azadmere) and fishing. [...]
Azadmere Kingdom Module KHUZDUL 3: The Coming of Men: [...] While Kiraz obtained most of its food by hunting and gathering the abundant wildlife of Equeth,
Azadmere's higher elevation and less bountiful environs had forced it to devote a large part of its valley to farming, fishing and herding. The Khuzdul have never been
fond of such activities, so some of the first Jarin to reach Azadmere were allowed to settle along the shores of Lake Arain where they gradually took over these
So, the Khuzdul must be excellent hunters and gatherers, since they were capable of supporting the large city of Kiraz that way (Kiraz was larger than Azadmere). They also
mastered agriculture and fishing, but have always strongly disliked these ways.
Lythia 2nd ed. KONDASGEL [B1]: The major Khuzan (dwarven) settlement of Ivinia. Kondasgel has nothing to do with the Ivinians, but still trades with the indigenous
Yarili. The smaller dwarven settlement of Harkaheim is bearby but not shown on the map.
Ivinia Index KONDASGEL [L6]: The greater of the two Khuzan cities in Ivinia, founded around 6700 BT. Kondasgel is connected to Harhakeim (qv) by a tunnel some eight
leagues in length. The lower reaches of the city are partly of Earthmaster origin. Kondasgel is ruled by King Inkanar, head of the royal clan Zynahul. It has a population of
about 2700 Khuzdul an a small Yarili population of about 400 who trade with the dwarves, and provide them with food by hunting, herding and fishing. SOme mining takes place in
the deeper reaches of the city.
Ivinia Index KUZJERA [L6+]: A forested, hilly an swampy region of southeastern Ivae. This wasteland is avoided by most humans other than the Yarili (qv). Kuzjera
contains the two Khuzan cities of Kondasgel (qv) and Harhakeim (qv). The Yarili in the region trade foodstuff and hides for dwarven products. Kuzjera is a refuge for exotic
creatures, notably the Ilme (qv).
Ivinia Index YARILI, The: [...]The Yarili are nomadic, travelling in small clan groups and following their reindeer herds. [...] The Yarili in eastern Ivae enjoy a
unique relationship with the Khuzdul in Kuzjera. They are the only humans the dwarves will deal with on any terms. There is a transient Yarili population in Kuzjera that
trades with the Khuzdul settlements of Harhakeim (qv) and Kondasgel (qv).
Ivinia Index HARHAKEIM [L6]: The younger and smaller of the two Khuzan settlements of Ivinia, connected to Kondagel (qv) by a tunnel some eight leagues in length.
Hahakeim was founded as a colony of Kondasgel in 3728 BT to mine iron and silver deposits. Altough there are still some valuable deposits of iron in deep lower caverns, the
silver has been largely exhausted, resulting in a steady decline in population to about 1300 dwarves. Harhakeim is ruled by an appointee of the king of Kondasgel. Since 692,
the governor has been Prince Ralin, the third son of King Inkanar. Harkaheim has a semi-transient population of less than 200 Yarili who provide food for the dwarves by
herding, hunting and fishing.
So, there is
some trade even in Ivinia. The Khuzdul patrolled the land until 430 TR and probably sustained their people themselfs as hunter gatherers, but seem to have
given up this way. Instead, they commit trade with the Yarili, which also act as intermediaries for limited trade. Food imported via the Yarili seems to be insignificant,
since the sources state that the Yarili produce the most part of the food for the dwarves themselves.
However, I'd really like to learn how these <200 guys keep up feeding themselves plus 1300+ dwarves all those years long... You know, cold climate, not very productive nature,
Ivinia Index KHUZDULThe: [...] The dwarves also practice a few crafts that are rare or unheard of among other races. Among these are the mushroom farming and
truesilver (platinum or mythral) working.
While this "proofs" that they do grow mushrooms, we get no notice about the extents and any details of this practice.
Lythia 2nd ed. LARHAKUL [E3]: A city of the Lythian Khuzdul founded in 7025 BT and the sister city of Erdar. Larkahul lies in mountains on the northwestern edge of the
Ketarh Plateau. The dwarves of Larkahul have never had much to do with humans, none of whom are aware of the city's existence. Larkahul has a vast network of tunnels and its
citizens rarely come above ground.
No trade with humans, but maybe with some other race? (I don't think so.) And most interestingly the "citizens rarely come above ground
". This could imply that some
outside supporters exist, but are not counted to the "citizens". However, they might be dwarves. (But nothing of this is written.)
Lythia 2nd ed. ERDAR [E3]: A city of the Khuzdul in mountains on the edge of the Ketarph Plateau. Erdar was founded in 7060 BT and is the sister city of Larkahul. The
dwarves of Erdar have built a vast underground network of tunnels, but have never had much to do with humans.
Once again: "Not much to do" may mean there is
some trade. Also,in this case assuming overground farming, hunting and foraging by the dwarves is not as strictly
discouraged as in the case of Erdar.
In the Azadmere module, some references indicate that Larhakul and Erdar have never had anything to do with the humans. There is even no legend or other kind of reference to
these cities in human history.
Lythia 2nd ed. MERDAIN [E4]: The original home of the seven nations of Khuzdul. Almost nothing is known of Merdain, even by the dwarves of the other cities. Merdain was
rumoured to be the place where the Khuzdul arrived on Kethira for the first time. Its location, or whether it is still inhabited is generally unknown. Legends of Merdain
describe it as a city of seven grey and silver towers wherein lived the seven nations of the Khuzdul. For unknown reasons, six of the nations departed to found their own
colonies. See: Azadmere, Kondasgel, Larhakul and Erdar.
Either Merdain has perished or established a total isolation. In the latter case, outdoor/surface activities are probably minimal, making for a unnoticeable/unconceivable
