Hi hi, long-time lurker here. I don't think this is the actual solution because it seems MUCH too straightforward compared to previous Legacy clues, but:
Take the two-letter abbreviations for each country:
Sweden - SE
Brazil - BR
Ghana - GH
Haiti - HT
Ethiopia - ET
-0-
Honduras - HN
Iceland - IS
Norway - NO
and you get SEBRGHHTET HNISNO. Disregarding the space/zero and unscrambling it, you can form the words THIRTEEN GHOSTS. You also have leftover letters B, H & N -- but maybe the location of the 0 before the last three flags denotes 3 spare letters..............
Again, probably not the solution, way too easy. But the letters spelling out a specific horror movie title is... something? (or nothing!)
