Footage of Lady N (http://img27.imageshack.us/img27/2472/hitgirl01.jpg; MK had http://i.imgur.com/1uyKp9N.jpg in the second Fireside Chat) in a Skype chat with MK. A distorted voice, presumably Lady N's, repeats "Michael". An automated voice repeats "You have one new message" (is this sample from Skype, in particular? [Note from OPG: I think that it's a voice mail.]). TES music plays in reverse in the background (it sounds like a combat track from Morrowind). The message at the end is "You said we would play it", most likely meaning, "You [all] said, 'We would play it.'"
Uploaded with the description "Michael Kirkbride and Lady Nerevar talk about Cyrus, Redguards, and more." (Referencing the Fireside Chats)

http://www.youtube.com/watch?v=9J-agukWPOY plays in the background, and the Bethesda logo as it appears upon Skyrim start-up is shown. A fountain pen writes "You said it would play us". A drawing (looks to be MK's) is shown (http://i.imgur.com/gaKQYqz.png). Includes a link to http://www.imperial-library.info/content/1-4-26-190, which is a picture of http://images.wikia.com/elderscrolls/images/1/17/PGE1-13.jpg from PGE1.

Footage of MK is shown. http://www.gamesas.com/user/707537-dinmenel/'s forum avatar is displayed many times, notably overlayed onto an image of http://elderscrollsonline.com/en/news/post/2012/10/18/reading-the-future-of-the-past-in-the-elder-scrolls, the Lead Loremaster for TESO. http://turnyournameintoaface.com/ was used to create the avatar, but neither "dinmenel" nor "Lawrence Shick" return the same avatar (though it's possible it's entirely random). Reversed Oblivion music is playing in the background, among other sounds - a voice saying "recording" (Lady N Skyping again?) and "I watched you as you disappeared", sampled from Tom Waits' "Watch Her Disappear" from his 2002 album Alice. The footage and the song is taken from http://www.youtube.com/watch?v=HXD3StsKCJk, which was also linked on the words, "seems like we can never have it again" in dinmenel's very recent post, http://www.gamesas.com/topic/1443737-tsirelsyns-bound/. Near the end, two images flash up (seen http://i.imgur.com/4ACtLvh.jpg and http://i.imgur.com/8U5BK69.jpg).
