Looking for the soundtrack of the L2 - Ertheia Episode

As title says,



I'm looking for the soundtrack of the current chronic, Ertheia.

I know there were a few that were added (a total of ten) and they often played on the dimensional warp (DW) and related.



NCJapan been promoting a sale "married" some time ago, on the tenth anniversary of L2 along with other items. Unfortunately here in the West could never find something like that can be purchased or downloaded these soundtrack.



I tried to seek the composers' names via iTunes, Amazon and GooglePlay, but I see that is updated to the Goddess of Destruction only.



So, what I would like from the players and other members of the board any specific information about it.



Thanks in advance.
