Paarthurnax waited cautiously on the mountaintop. He stared expectedly at the time wound as the minutes went by. Suddenly it shuddered and the snout of a dragon poked through. The dragon revealed its spiky black head and ominous red eyes. The World-eater flashed Paarthurnax a toothy grin.
"Alduin. As anticipated you have found your way into this time." Paarthurnax said tonelessly. The dragon crawled fully out of the time wound and onto the snow covered ground.
"As anticipated the Nord heroes who fought me have made a grave mistake for mankind." Alduin laughed.
"They did not know what the Elder scroll would do. They thought they were banishing you from this land forever."
Alduin chuckled loudly. "As if I, Alduin, son of Akatosh, could be banished from this world when it is rightfully mine!"
The joy of seeing his brother had faded and Paarthurnax was reminded of why he had turned traitor to Alduin. His brother was far too arrogant with his power and believed that he could not be overthrown. But still, family is family and since he could not see his father Akatosh, god of time, Alduin was all he had. Then he remembered his loyalty to the Greybeards and all joy that the sight of his brother had brought him vanished. Paarthurnax was torn from his thoughts when Alduin began to speak again.
"I remember when you had betrayed me and helped those pathetic mortals overthrow the dragon cult. However, I will allow you a second chance. Join me once more, Paarthurnax."
Paarthurnax was not at all surprised that Alduin would seek to rule all of Nirn once more. In fact, it had been predicted by an Elder Scroll. Although Paarthurnax was not completely sure his brother could do it. He knew that there was still hope for the Nords of Skyrim. Off in a distant land there was someone who could defeat Alduin.
"Alduin, you are much too arrogant with your power and I will not betray mankind. I had made my choice long ago and I will change my mind a second time. Not now, not ever!"
Alduin grimaced at his younger brother. "You will see that you have picked the wrong side when I have conquered all of Skyrim and the Nords bow to me!" He shouted, his voice filled with rage.
"There is another who has a Thu'um as powerful as you." Paarthurnax hissed.
"The Last Dovahkin stands no chance against me! They are not even part of this world!" Alduin screeched.
"But they are in it. Just over the mountain side." Paarthurnax said almost calmly.
With that information apparent to Alduin he took off from the ground and soared rapidly towards the Dovahkin.
