While the minor elves were being enslaved by Kris Kringle and hiding in hollow trees, the other branch of the elf family, the major elves, enjoyed wow golda surge of popularity because of the writing of J. R. R. Tolkien.
Tolkien describes the race in his Middle Earth tales (most notably The Hobbit and The Lord of the Rings) as beautiful, elegant, immortal wow powarrior-poets. They're interested in archery, lore-making, architecture, and orc-disemboweling.
