"I was his lieutenant." Saying just that may not seem like much. Certainly not with the plain way Paarthurnax states it, as if his name wasn't known throughout all of dragonkind and mortalkind both. As if the Blades never referred to him as "legendary". "He was the first I had known for all my life. We had cared for one another as much as our kind could allow. It is not an easy thing to turn your back on one so close... is it?"
