Could they still exist?
Let's face it Elves in many fictional Worlds either are or once were the height of civilization, always do we hear about their sprawling majestic kingdoms filled to the brim with magic and beauty. How the Elves either are immortal, magical beings, close to if not are the epitome of perfection in both physical form as well as mental acuity. There societies being described as everything you could want them to be from a outward appearance, that is to say there is as much intrigue at Elven Court as any other high society. While disagreements and woeful maneuvering took place at it's core Elven Society was good aligned (not sure what else to call it.). Yet almost every such world with similar depictions at some point or another, introduces the idea of the fabled or perhaps reviled, "Dark Elves" ..
Dark Elves, usually depicted as every bit as beautiful as their "Elven" counterparts are always either visually darker or slightly more tan if not bronzen. They usually have several other traits that physically mark them as well varying depending on the world in question. In same they have snow white hair, red eyes, ebony black skin, and are slightly more lith or shorter than their normal elven counterparts. In others they appear dark blue or grey in skin, with hair colors they vary from white to silver to dark black and any color in between. Still besides their physical appear what truly always makes them stand out in most fictional worlds is that they are incredibly "evil". What exactly makes them evil both as a source as well as from a cultural point varies as much as their appearance. The most famous one that im most familiar with is from the classic D&D Forgotten Realms setting. Without going into great detail, they are and can be downright twisted. Their culture however can be viewed as well fascinating in some aspects though, at least in that particular world.
So my idea is could such a group exist in Thedas? Hidden away somewhere, yet discovered by modern Thedas? Forgotten by what remains of the Elves? Imprisoned in some far flung corner of the world, or beneath the Earth? What part could they play in the over-all problems still plaguing Thedas? I was briefly daydreaming about this very thing. Especially after remembering Paivel's recanting that the Elves once varied as much as the humans and were everywhere across Thedas, though he says he's never heard of Elves living in caves, (despite you finding such a ruin where Dwarves and Elves apparently must have traded there and maybe even lived there). I like to imagine them as still every bit as powerful as the old Elvhen, perhaps having even being untouched by the rising of the veil or simply countermanding it with their own personal "Dark Weave" of spells that kept all their magics in place. Perhaps they are somehow even responsible for setting the Dark Spawn upon the world and watch and wait for a time when there creation finally takes over the surface and terraforms it into something more to their liking.
Still what do you guys think. Could Thedas have their own version of Dark Elvhen someday? How would you prefer they be handled if ever they did come into existence or be revealed to always have existed?

Are you asking if Skryim somehow co-existed in the DA realm?
