Choosing Place Names
From The DarkMod Wiki
Just like choosing the names of characters, choosing appropriate names for places can really add an extra layer of believability to your mission.
Towns and Cities
Older towns and cities will have names with a Latin or British influence, especially those closer to the center of the empire. (eg, Aberarad, Halstead, Coniston, Vinovia, Lindum). Cities that have a large port often have "port" at the end of their name (Bridgeport).
Towns on the western or northern edges will probably have names that sound more Germanic (eg, Flensburg, Braeden, Esslington)
