[X] … the Olokki Monument. A tower jutting out of the sea, containing a refinery and storage facility that they could dig up for refined metal for widespread use and wait a minute. This description, the location on the map… isn't this that sword-shaped structure off in Vimanos Sea? Were the goblins the ones that built the goddamn thing?!
[X] … Kalaresh, a region known for its metallic wood. A magical grove spanning a sizable portion of the continent, and the main subject for lightning storms over the land. The goblins could trade with its keepers, or could ah, 'acquire' some of the trees in secret. Either way, they would get their resources, or they could certainly obtain it through other ah, 'alternate methods'.
