These are a couple of locations (or similar ones) that I would like to see supplements for. They are the cities of two races who haven't been covered much as yet - Nomari (Dwarves) and Dyari (Dark Elves).
With the Dwarves, about all that can be said is that they exist on Kulthea. They haven't otherwise been covered. My current picture of them has been influenced quite a bit by Morrowind.
The Dyari have been covered more, as there are a number who crop up in various places, but they still lack the detail of other races, even other races of elves - and they are a more interesting type, given that they can be bad guys, but are not necessarily evil.
