All i can find is :

http://eu.finalfantasyxiv.com/heavensward/ and http://forum.square-enix.com/ffxiv/t...=1#post3039574

as it is a new race there isn't still much information besides the oficial informations and some lore details you casualy find in game.

fun fact: the example they gave on the post : Yatsurugi no Yuki AKA Yuki Yatsurugi is a Doman princess from the Ninja quests.
