Dear Santa Greatfather Winter,
... I don't even know where to begin, I've never really done this before. This does feel remarkably like the one year Taelan tried writing you to make sure you'd come and visit after Myranda told him all sorts of gnomish and dwarven tales while I was away. I swear she and Karandra were laughing at me as I tried to think of something to tell the boy.
After what I saw in Northrend, what I read about Ulduar and the Watchers within, I don't doubt that perhaps somewhere you exist or existed.
Maybe some apple cider, and gingerbread for everyone on board, I think. It's simple and something I hope they will enjoy.
For the infirmary, a supply of healing potions from my world. With notes on them so they know where they're from and what they're made from.
To the Doctor, a book on the myths and legends of Azeroth, perhaps? Like the ancients, such as Goldrinn and Elune.
For Agent K and Ardent, a few bottles of dwarven alcohol from my world. Dwarven stout, and thunder ale. Maybe give Ardent a copy of the research I got from Brann on the Titans and Ulduar. It certainly couldn't have been published yet.
For Arthas... Light above, he certainly doesn't deserve anything, and I'm certain that just about anything he could be given could be turned into a weapon. But, return him his old paladin libram. Maybe make sure it can't be destroyed.
Back home, I just hope everyone is alright and that my people, the Argent Crusade and even the Ebon Blade, can have a happy Winter's Veil. ... And give Darion something, Light knows what he could even want in the first place, even if it's just a clockwork toy.
Sincerely,
Highlord Tirion Fordring
