Paarthurnax is a Quest in Skyrim.This is an optional quest, however it must be completed before ending the Main Quest in order to continue the Blades storyline.
Delphine and Esbern have discovered that Paarthurnax was one of Alduin's chief allies during the ancient Dragon War. They refuse to give me any more help until I kill Paarthurnax.
