I saw that she had pointed ears indicating that she was indeed a mer.
I also noticed that it's teeth were some what crooked if not jagged... A trait only today's Falmer carry.
In addition, I took note of her skin color. It was pale, with a blue-greenish hue (which probably came with the necromancy).
The only other race of mer that share this pale skin trait are the Dunmer... Rarely did I see completely pale Dunmer but, it was still a plausible possibility.
So, I began to come under the conlusion that the wispmother is either an undead Dunmer or a Falmer Snow Elf until.... I noticed something odd about it... It had claws, which is something even vampiric Dunmer lack. And it just so happens that the Falmer that we see in these dwemer ruins have clawed hands and feet... An adaptation? I think not... Remember? The Dwarves poisoned them with these mushrooms. Causing them to become blind and develop a gollum-like hunch. The only possible role evolution had was their increased sense of smell and hearing.. Or perhaps the clawed hands and feet came from a lack of nail clippers and up keep? I don't know...
So what do you think? Are these Wispmothers the hidden remamemts of the ancient Snow Elves? Or are they simply lost spirits from oblivion? Also, Do think this is some secret part of the Dawngaurd Dlc?
EDIT: (Please, if you skip anything really try not to skip reading this!)
Also, another really interesting theory just hit me like a brick... Ok, so if you looked into that whole elderscrolls online announcement you'd know that Bethesda intends on integrating multiplayer in some sort of fashion. Awesome right? Well it gets better, another very interesting comment I caught was that the plot behind the next TES will take us to a time before the oblivion crisis.....
Yeah? So....
Don't you realize it? This opens a HUGE window of opportunity for Bethesda to start from scratch again.
That means this whole "TES online" scheme could be Bethesda's secret way of re-introducing the elusive Dwemer and restoring the Falmer to their much more nobel title of Snow Elf! It's the perfect way of adding two more races to our character board!
Thoughts?!?!?
