Has anyone noticed that the symbol for Skyrim is on the doors around the imperial city? Not sure which doors exactly, but I did notice one near the door to the Waterfront.
Anyone else find anything else?
It's the Seal of Akatosh, it's been in every game. You can see it on the sails of the ships in the Redguard opening, it's on the box cover of Morrowind, it's on the doors in Oblivion as you mentioned and so on.
I thought that was pretty cool. I don't know why it ended up in the sacred place of the Tribunal though. I never thought Almsivi was on friendly terms with either Akavir or Akatosh.
It's because they are part of the empire, so they will display the Septim Empire's symbol.
