I should save my game in a whole new slot
I think they justified that by claiming that the events of Oblivion has made it harder for Daedra to breach into Tamriel.Clannfears, Hungers, Deadroths, Golden Saints, Scamps, Winged Twilights... The Daedra all had their unique servants, and now? Nothing besides Dremora.
Also for all of my complaints of Skyrim, I will admit that Blackreach was pretty cool. Sadly not much was done with it aside for being a locale.
Balmora, Ald Ruhn and Sadrith Mora technically counts as cities too (I'm guessing that major cities were small in Morrowind in order to improve performance). There are Morrowind mods aimed are rectifying that.the last time they even tried was in Morrowind with Vivec.
