Back in 2016, Blizzard released the Khadgar alternative Mage portrait for Hearthstone. Initially only available in the west as part of a World Wildlife Fund charity effort, it subsequently became available in China this summer as part of a Hearthstone / Heroes of the Storm cross-promotion.
Now it's available to purchase once more in South Korea, and as part of a fundraising effort to support firefighters in the country. Full details of the promotion are available over at the official - Korean-language - Hearthstone site.
According to Hearthpwn, however, there have been reports that the unlock code purchased through the Korean shop can be used to unlock Khadgar in any region, but we'll echo their warning that you do so at your own risk. If you want to try this "grey" route, check the current listings on Khadgar-Mage-Skin-Hero-Skin-/112586026039?hash=item1a36a66c37:g:Zv8AAOSw-ChZzrH2">Ebay or hook up with a friend in the region.
