In
Oblivion, we learn that the whole of Tamriel is under attack by Daedric forces (whether Akavir, Atmora, Yokuda etc are or not is unknown). Morrowind is hit particularly hard, with Vivec being 'taken by the Daedra', Telvanni wizards struggling to close the gates and the entire city of Ald'ruhn destroyed, despite waking Skar. We learn that Skyrim isn't doing much better, with the 'old reaches' (or was it marches...difficult to remember the Oblivion rumours) under siege.
So, in Skyrim would you like to see a landscape scarred by smouldering Oblivion gates, surviving Daedra roaming the frozen mountains and forests? Towns being rebuilt, relatives still mourning, heroes still venerated?
How much of the Oblivion aftermath should be seen in Skyrim?
