Slight spoiler ahead.
I've just completed this on a new alt and was surprised to hear Mehrunes Dagon start speaking after turning in the quest at the end of the dungeon. I'm not sure if this was an easter egg or has something to do with the prologue but it was a sweet surprise

Yeah it’s been in the game for a long time and sadly you only hear it after the quest which is a shame seeing as it’s a nice touch.
Mehrunes Dagon in City of Ash does not have anything to do with Blackwood, because that's the way the city of ash has always been. There has always been an oblivion portal in there. The story has always revolved around Mehrunes Dagon and in the City of Ash 2, where the story continues, you'll explore Deadlands.
Do keep in mind City of Ash was released with the game (around 2014?) and city of ash 2 was released later on (around 2015?). Blackwood was released 6-7 years after.
