In patch 4.0 we got into small Raen village and dungeon for them, but I'd like to ask that are we going to get more during Stormblood? For example in Wiki it's mentioned that Raen would have settled to mountainous eastern reaches, could we possibly go there during expansion?

"Unlike their sister clan, the Xaela, who bloody the land with their endless tribal conflict, the Raen have embraced a life of tranquility and solitude, long abandoning the nomadic lifestyle of their ancestors to settle the deep valleys of Othard's mountainous eastern reaches."
