Winter Elf (5e Subrace)
From D&D Wiki
Winter elves are extremely distant cousins of Wood elves. Many, many, many millennia ago a clan of Wood elves ventured into a frozen wasteland near their home as food became scarce from humans moving into their territory and depleting the resources. Winter Elves are described by humans and other races that see them as hauntingly beautiful apparitions, since their separation from the forest years before they have become a bit stockier than their cousins, having developed a thin layer of natural fat for insulation, their skin is pale to white with long extremely pastel hair ranging from white to rainbow colors such as pink, blue or purple and their eyes are usually purple, blue, magenta or white. They are very nimble even with the layer of fat, hunting in the deepest of snow and harshest of blizzards with ease and making homes in caves of ice or stone.
