Remember in the trailer and when you read the Elder Scrolls, does anyone know why Markarth, Solitude, and a cave in between (Possibly Pinemoon) were glowing red.
In between there is the location to Darkfall Cave, which leads to the Forgotten Vale, the location of Auriel's Bow. Markarth and Solitude glow red for reference-it is a zoomed in version of a map of Skyrim.
