Yes, well, I did say that there was probably going to be a similar event this year. However, the NPC's must still serve a purpose, or else they would not have dressed them up. There were also some new ones added this year I think as well, so I just decided to put them into one big list. I am guessing it will be something to do with the players house, and maybe once the entire server has reached a certain amount of something, that gauge in the Elder Council will fill up and unlock something, either that or it is a player achievement/mini quest.
