First, you have to speak to one of the rich children (given that there are childrens models added to the clients) complaining that they haven't seen their parents, they also said that they last saw them going out to buy presents through the mountains.
The player finds the parents in the mountain near the black knight castle and dwarf mining area, only to find them trapped by 3 creatures (possibly a white creature.) and saying "Help!".
The player kills the 3 creatures and talks to one of the parents saying if they're okay, they will say no they are badly wounded and need to seek medical care. The player must go back to duel arena to talk to the medical officer there and ask for those med pack (You get from camp or castle war). Then you return to the parents and treat both of them, in return they give you details about possibly finding the where abouts of Santa. They say that there is an NPC hiding in the alley (where Black Arm Gang headquarters are) they tell him the secret codename "Insignis, Santa, Nativitatis" (which is latin for: Gem, Santa, Christmas). From there he sells a enchanted gem that allows communication with Santa)
The player uses the gem and Santa says "Who is this?" obviously, the players name. Santa will then say that he had never communicated with civilisation before, therefore he asks for help. He asks the player if he can write down the wish list of the following NPC before "the game's christmas time" comes. (15 Random NPC.). Every NPC will give the player a small gift (possibly money) to make it worth their while.
After that, he is denied use to the gem until further notice.
The player talks to the NPC, not mentioning Santa and ask them for their wish, and writes it down, doing the same for the rest of the 14 NPC.
After completing that part of the Event, he is allowed use of the gem to speak to Santa again.
Santa thanks the player and asks them for 1 more favor(After finishing the conversation, he is denied use of the gem again.), to kill the Evil Jack Frost (some white NPC).
That has 7 helper/servent NPC protecting and healing him and has a hitpoint of 500 then where he drops a note plotting his plans against Santa.
After killing Jack Frost (Boss), he drops a plot, after the player picks up the plot, he is allowed use of the gem again. He tells Santa about the whole thing and Santa asks the player to meet him Face to Face. He asks him to meet him in the Ice Path (Which is I believe the home of Santa of WorldScape currently for the past Christmas Events.)
After meeting Santa he gives him the plot and Santa rewards him with interactive item which is N/A. (i am writers blocked about this part, feel free to add in as long it's interactive.). Santa also tells the player to give the parents an "early present"and to tell them what happened.
The Player go to one of the parents located back to where the children are and tell them about Santa, and giving them the "present" After the parents take the presents, The player is granted access to the presents room, which he can pick up as many presents (containing common items) and using it on other players or for self.
Event Complete.
