Started playing Oblivion again for the hell of it and i started noticing the dragon logo from skyrim all over the place.. Something i never really saw before or never looked for. Now that its plastered all over Skyrim i am back in Tamriel and seeing the same thing. Pretty cool

That's the red diamond crest the empire uses, it was in them as far back as morrowind i believe

Yep, the imperial dragon crest is even on the TES III box cover.

Ironic that some would think the empire is ending too. Seeing that their symbol is the game cover (and no, I don't think I'm reading too much into it).

edit: Ah wait, then again Oblivion's symbol was on the last game. And they were the big bad. Hmmm...
