Question about assassin armor

ok i want to know where you can get this armor that i linked below. from what i have seen this is the nightstalker armor. i want it this skin, but i cant seem to find it. i am wondering if it was only skinned like this in the preview event. but, if anyone knows the answer to this, please let me know.

yea i had the same question, there where really cool monk and ranger armors and i wanted to get one in factions but... theyre gone! can we get them back in any way?

<bump> still havent learned the location of this armor skin.

ok after doing some research of my own instead of waiting for someone else to do it for me, i have determined that this seems to be the 1.5k luxon. this in a way disappoints me. and for all of those who say this is luxon 15k armor, they are wrong. the 15k variant of this armor is very different. below is an image of the male and female 15k luxon armor.



since i have figured this out, i have a whole other ste of questions entirely. i believe that some of these questions are better said in another thread, because they will most likely help others as well.
