Well, part of the carving on Alduin's Wall depicted Red Mountain, a central part of Morrowind's storyline. In fact, it is a symbol that means Morrowind's story was one of the signs of Alduin's coming. And you know who started the Nerevarine on his quest to screw up the liminal barrier? That's right, Caius Cosades and the Blades!
Were they sort of stuck between a rock and the hard place? Had they not discovered Alduin's Wall yet? Or were they just plain dumb right then?
What do you guys think?
