I was informed that 934-38FB-C9F4 was for a starter kit giving loot like planks, stones...plus 100 gems and that this was a code given at the start of the 20th anniversary event around June 27, 2013
Both GamesRadar.com giveaway & FreeMMOstation.com had a limited amount of codes for a prize package that was just like this description and around that same date.
I am inclined to believe that this one code might have been a personal code. The fact that, when others type it in, it tells you it's already been redeemed instead of being invalid is what make it so confusing and seeming to be a good code for new players to use.
We have tested this very code with brand new players and I can confirm that they too have gotten the message of already redeemed.
Therefore I won't be adding this code to the list since it is looking like it might have been part of the outside website giveaways that are posted in the expired section.
