Does this picture look familiar to you? Yes, it's the Imperial City from Oblivion. Well guess what? It's in Skyrim too! People have been snooping around in the game files and discovered that Skyrim actually comes with landmass from both Cyrodiil (TES IV: Oblivion) and Morrowind (TES III: Morrowind) and possibly even more. The original post describing the discovery contains additional details that may hint at possible DLCs exploiting those areas of Tamriel.
