Forgive me if i'm being dense, but that has a 2004 stamp, and the Oblivion logo - so what is the "Five" and the text about the Dragon Prince in her veins, and the Empire extending in runes all about?
EDIT wait wait wait I get it. Change the URL slightly and it counts down. Change the 5 to a 4, then to a 3 etc.
Dunno what it is, but I don't think it's TES5.
