User blog comment:Timeoin/Is Dawnguard the first DLC/@comment-64.12.112.170-20120409190629

I don't see this being Mythic Dawn. *oblivion spoiler* just in case. They already said that the oblivion gates are closed forever due to Martin channeling Akatosh's spirit. Whats the point of having a DLC, which they have already said will be big for Skyrim, on a subject thats already closed for good. The Oblivion Crisis is over, Dagon lost and thats the end of that. Dawnguard has to be about something else. If memory serves correctly, it has been mentioned in Skyrim that the Mythic Dawn was hunted down and destroyed anyway.
