Although the 1981 Expert Set did not reprint the Known World map in any form, it did include a 6 mile per hex map of the Karameikos region. In addition to X1 (1981)’s cities of Specularum and Selenica, this larger scale map introduced a number of new settlements to Karameikos, including Luln (marked as a town); the Haunted Keep and Wereskalot in the neighbouring Five Shires (both ruins); and Fortdoom, Krakatos, and the Estate of Marilenev (all castles). The Black Eagle Barony is named, and labels appear for gnomes, elves, dwarves, kobolds, goblins, orcs, bugbears, and frost giants.
Interestingly, the Lost Valley is shown (though hard to make out) and labelled — and it’s across the border, in Darokin.
The text on page X60 provides some level of detail for some of these names, as well as a few more labels to add to the map: Gulf of Halag and Black Peaks/Cruth Mountains/The Steach.
The text also sets up the Black Eagle Barony and defines its relationship with Luln, and notes that the Haunted Keep is also known as Koriszegy Keep. Amusingly, half of the page is given over to the gnomes, although there is no mention yet of the name of their settlement.
