Note on names: Each nation in Aerda is based on some historical nation from the ancient world. Danannsidhe and the Vales are decidedly Gaelic, and the names reflect that. Nûmidëan names are of Anglo-Saxon origin. Nifflgarde names are obviously of Norse origin. Sildaran names can be of Gaelic or Norse origins, or a combination of the two. Cychloan names are generally Greek in origin. Vilandrian names tend toward Latin or Spanish.
I've included pronunciation guides for each of the names below, to help.
