Plains of Snow

The Plains of Snow are a location, somewhere on Azeroth. This arctic land is starkly beautiful, but merciless as well. Its unlikely anything could survive the brutal weather without a thick coat of fur—or the aid of magic.

World of Warcraft
The World of Warcraft Alpha back in 2003 contained a snowy map in the game files, which named the place "Plains of Snow" on the minimap.
