How in the world did people figure this out?
Extracted the game files and checked it. It is a popular method to find what future DLC's will be about in many games.
This is how we knew what Dawnguard will be about before it was even announced.
This, but it makes me curious what became of the Skaal tribe we met in Bloodmoon. Perhaps they are still kickin' and tolerated the Dunemr?
Knowing TES5, the story will have Dunmer Vs. Skaal conflicts. But than, Skaal never went out of their village besides when they destroyed Fort Frostmoth.
Skaal will probably hate the Skyrim Nords tough. They gave the Dunmer Solstheim even tough Solstheim was never part of Skyrim.
