Hello everyone. I've been trying to come to terms with the fact that the Raen just don't seem to have an identity in FFXIV.
Sweeping statements like this necessitate some sort of backup, so allow me to explain.
We are introduced to the Raen and the Xaela in Heavensward, but the most we get out of the Raen is Yugiri. However, she is known as a Doman, rather than as an Auri. Her looks would be rather striking in Eorzea, seeing as the Auri are rather rare here than in other continents, but I do not immediately recall anyone ever making any such comments about her being an Auri, much less a Raen.
The only significant lore we get is through the ninja quests which involve Princess Yuki and her subjects, which I did enjoy quite a bit. However, we still didn't get much recognition of them being Raen, but rather as being Doman/Far Eastern.
Going into Stormblood, we finally get something about the Raen with Sui-no-Sato, even being described as a village of Raen. This was akin to desert for me, as I finally found a place where I thought we'd get much more knowledge about Raen culture and their way of life. Unfortunately, what we did get to know was rather scant in comparison to the veritable love letter to the Xaela that was the Azim Steppe.
We are also made aware that there is a population of Raen in Sharlayan through Mikoto in the Ivalice raid series.
Ironically, as we move into Shadowbringers, we actually get a wealth of lore on the First's equivalent of Raen in the kingdom of Voeburt, which I adored. It felt quite right for the Raen (even though the royal family of that fallen kingdom apparently had the scales of the Xaela), and I eagerly snatched up all the Voerburtite sets relevant to my Raen character.
Further on into the patch content, we are introduced to a new population of Raen in the Sorrow of Werlyt questline, with names that are much more similar to their First counterparts and that they aren't as confined to the Far East as they were previously portrayed as being.
