I am starting to really personally dislike some writer or writers at Bethesda, however. Don't know who yet as no one seems to be talking about who wrote which parts of the quests. But this was ugly and uncalled for and made me angry. Bad enough that the Blades seem to think you're some schmo and not the true Emperor. But to have them say you need to kill the dragon that saved them from the last kalpa and they're going to take their little toys and go home even if it means the end of everything is too much. I want to introduce Delpine's face to my ebony gaunlets until she sorts out her priorities and remembers what loyalty means.
Seriously, this was game-breaking for me. It ruined the immersion that the writers were such jerks.

the Blades, no no the blades are long gone and dead, I even recovered one of the last blades weapons. Delphine and Esbern can go kill themselves.
