Serenity is the name the Alliance gave to my Warcraft fanfiction village of night elf OCs when their race joined that faction. For those who read my fanfics, you know in my telling that eventually, the night elves leave the Alliance and the undead leave the Horde and there are four factions again, just like Warcraft 3 (which I liked more than World of Warcraft).
I imagine the night elves, as a nature based society, as living in a series of small, naturally grown groves holding low populations and I am one of the very few writers who hold to the official canon trope of all, or at least 90%, of the men being in hibernation before the Third War
