I'm trying to decipher what you are asking but it's very hard cuz I have no idea what language your speaking.....but what I am interpretting from your question is that your looking for the Oblesik for the Order of the Fang....if so, you have to go into the Vault of Ice and defeat all of the Banshee's again to get to the last one (the one with the yellow, brown, goldish hair and greenish robes), beat her and her minion, and then you'll be able to go up to the Oblesik behind her to get your etching you need.
I hope I deciphered this right...if not, I'm sorry
