Disappointed with how ruthless and unforgiving the Blades were at the end of the main quest? Felt like you should have been able to put your foot down and make them see reason? Well now you can!
This mod is a simple, yet badly needed modification to the post-MQ quest the Blades give you to kill Paarthurnax.
Approach the quest as usual. Listen to the Greybeards and Paarthurnax.
Should you decide to spare his life, return to Delphine or Esbern and explain it to them. You may have to be a bit forceful in the process. They may not like what you're telling them, but they're supposed to be there to serve the Dragonborn, right?
Should you choose to go through with slaying him, he will not be alone. Paarthurnax told you he was going to try and teach others the Way of the Voice, and he'll have his first group of students listening intently. Or, well, whatever dragons do when they're perched on rocks looking at each other.
Are you a ruthless savage like your Blade companions, or will you show compassion and forgiveness the Blades don't appear to be capable of anymore? Make your choice, Dragonborn!
