Dwarves have a winter festival where they tell stories about Greatfather Winter; in recent years, more and more humans have been participating in this event.APG 199
The term "Winter Veil" is said to stem from a supernatural being referred in many cultures to as Greatfather Winter. As he would walk the land late in the seasons, winter itself would be his billowing cloak. In his wake was the blanketing of the land in snow, and thus it is said that Greatfather Winter would cast his wintry veil over the land. As Greatfather Winter walked Azeroth, it is said he would provide a bounty for those who welcomed his presence. As such, the idea of feasting during the winter veil would bring together communities as they shared whatever they had. Typically, a single day of merriment and feasting welcomed the change, all in anticipation of the land's renewal.
The image of Greatfather Winter is sometimes used, as a harbringer of commercial exploit rather than as a supernatural titan. Greatfather Winter visits the great cities of Ironforge and Orgrimmar - courtesy of the fine folks of Smokywood Pastures and he spreads cheer in celebration for the Feast of Winter Veil. But, all the cheer-spreading makes Greatfather Winter hungry, and he looks for adventurers to get him his daily fix of milk and cookies.[1][1]
Greatfather Winter is now seen as a kind old dwarf, or orc, who brings presents to everyone. Although many people, such as lorekeepers, have their thoughts about this commercializing of him by the Jinglepocketgoblins, it is a nice idea nonetheless.[citation needed]
Speculation
This article or section includes speculation, observations or opinions possibly supported by lore or by Blizzard officials. It should not be taken as representing official lore.
It is possible that Hodir is the original Greatfather Winter (which goblins later commercialised) as he has been referred as "father figure" and connected to ice and snow. He also refers to veil of winter in Ulduar.
Trivia
He is an obvious reference to cultural and religious icon Santa Claus, due to his look, his location, and the event itself.
