Yo, Fernehalwes!
We have naming conventions for Eorzeans and the five races, but curiosity has me wondering what Garlemald follows in regards to names. It seems like sort of a melting pot of cultural names (which I'd assume is due to them having annexed so much land into their empire?), but some things seem to be common.
We've seen plenty of Garleans flee the empire (such as members of the Garlond Ironworks, and obviously Cid Garlond himself), so I imagine it wouldn't necessarily be a rare occurrence for Garleans to pop up in Eorzea while seeking refuge from the empire. Suffice it to say, I could see some players wanting to have a character with "Garlean" lineage.
As far as names go, I've taken note that a lot seem to have romanic roots. Gaius, for example, is roman in origin if I'm not mistaken. Solus, the given name of the emperor, is latin for "alone". The empire's military is constructed much like the roman legions, so this isn't really all that surprising.
However, there seems to be other influences on their names. For example, Gaius van Baelsar and Nael van Darnus. "Van" is a common prefix to surnames for the dutch. Does this mean they have both dutch and roman influence? Or was this simply an aesthetic touch to Garlean culture, and their actual names don't have dutch influence?
But what about Nael van Darnus himself? I think it's safe to assume he is Elezen (given his motions in-game, and the fact that he's all lanky. Would be weird to have a Hyur who's limbs are that elongated.), and seems to be further reinforced by the fact that Nael is french in origin. French being what Elezen names are based off.
This thought brings into question whether racial naming conventions that are common in Eorzea are also common in Garlemald. Why would Nael, a member of house Darnus (which is presumably a very powerful family in Garlean society), have an Elezen name and not something more fitting of Garlean naming conventions?
