Ok I play skyrim on the ps3 and I was wondering if there is a way to be a blade and a greybeard without killing Paarthurnax. The quest called Paarthunax states that I have to kill him or they won't help me and the Blade's questline will not progress. I want to keep Paarthurnax alive and be a Greybeard but I also want to be a Blade. Will completing the Greybeard questline prevent me from having to do this quest? Will doing the Blade's questline first prevent this? Please help me with this!
