(Anything not described below is from the Gazetteers. Anything not sourced was created for this map.)
Ergythia: elf-friendly border village (Note: like "Ar-delphi-a", taken from Classical Greek city -- Gythium)
Keeps and Towers:
Elfwatch: A small keep dating from the Elfwar, it is now more a ceremonial and diplomatic center than an actual fort.
Garron Keep: Small stopping point between Ft. Runnels and Corunglain, mostly for supplies. Named (like most keeps) for a heroic general.
Lairs and Ruins:
Delmar: Ruins dating from [xxx]
Monument of Friendship: Ruins from before the Elfwar, once a marker of the friendship between Alfheim and Darokin. It has since been turned into a memorial of national friendship fallen and renewed.
(Humanoids along the border w/Broken Lands, and in hills to west (see Ardelphia region))
This area should be loaded with history, being a central breadbasket region and a border with the humanoids to the north. The hills are probably dotted with additional long-forgotten ruins. See also posts beginning here.
