Lyara opened her mouth to hail a greeting to the champions, but no words came out. They walked right by her as if she wasn't there. She then realised that she was just an observer to the events from long ago, and would not be able to participate.
She witnessed the discussion between Felldir and Hakon, after Felldir first suggested they used the Elder Scroll against Alduin. Hakon was against it, convinced that they would win the day with steel.
"Alduin approaches!" Shouted Gormlaith.
Alduin landed in almost the exact spot that she had left Paarthurnax in her own time, on top of the rocky wall. So huge was the dragon god, that Lyara felt the ground beneath her shake as he landed. The great beast spoke to them in dragon tongue, disdain evident on his reptilian features. One heave of his wings and he started to ascend. Soon, he would rain down his deathly fire, and the heroes would be crushed.
"Let those that watch from Sovngarde envy us this day", cried Gormlaith. "JOOR ZAH FRUL," she shouted.
A blue glow seemed to encase the dragon, and with a deafening screech he landed on the clearing where the warriors waited for him.
"What have you done? What twisted words have you created?" Alduin screamed, shaking his head. "Paarthurnax! My teeth at his neck!"
Lyara was riveted by the scene. Paarthurnax had betrayed Alduin it seems, and he had been the one to teach the humans the Words of Power. The dragon god continued with his threats.
"But first, you will die in terror, knowing your final fate... to feed my power when I come for you in Sovngarde."
Lyara was horrified. As she watched Gormlaith and Hakon charging, their swords swinging, she knew that should they die, Alduin would seek out their souls in Sovngarde, and eat them.
Felldir cast spells at the dragon, before joining his two companions in the melee. Their swords were proving to be no match for Alduin's tough hide. They were causing damage here and there, but nothing fatal.
With a swipe of his large head, Alduin snapped at Gormlaith as she got too close. He clamped his mighty jaws around her middle, and Lyara watched helplessly as Alduin shook the warrior maiden and threw her like a rag doll against the wall. Her body fell in a heap, unmoving. Hakon renewed his attack with increased vigor, but it was evident that they would not succeed. He yelled over to Felldir that perhaps they should use the Elder Scroll after all.
The Mage ceased blasting Alduin and pulled out the scroll. In a loud clear voice he begged the Divines to remove the World-Eater.
"By words older than your own we break your perch on this age and send you out!"
Alduin shook his head, and roared in denial as the mage continued his incantation.
"You are banished! Alduin, we shout you out from all our endings unto the last!"
With a brief shimmer of green light, Alduin vanished.
As soon as the dragon disappeared, Lyara's sight started to shift back to her own time. She felt the familiar large hand of Farkas at her elbow as she teetered, feeling weak and dizzy for a second.
Paarthurnax lowered his head to look at the elf.
"Did you learn the shout, Dovahkiin?"
Lyara nodded, her strength coming back to her. Her dragon soul remembered the words she had heard Gormlaith shout.
"Yes, I did. I witnessed the banishment of Alduin."
Almost as if the very mention of his name had conjured him, a great screech ripped through the air as Alduin appeared above them. Paarthurnax immediately took to the air with a challenging roar, preparing to face his old leader. Lyara recognised the dragon that had attacked Helgen.
"My belly is full of the souls of your fellow mortals, Dovakiin. Die now, and await your fate in Sovngarde," threatened the dragon god.
Alduin followed his taunts with a belch of flame and molten rocks. Lyara was able to leap out of the way of this blast but was not sure she would be able to avoid another.
"Use Dragonrend, Dovakiin. It is the only way to defeat him," cried Paarthurnax as he blasted at Alduin with his own flames.
"JOOR ZAH FRUL", answered Lyara as she aimed her shout directly at Alduin.
With a terrible cry, he crashed onto the snowy mountain top, and skidded to a halt only feet away from where Lyara and Farkas had taken shelter from his deathly flame. He was surrounded by the strange blue glow, caused by the Dragonrend shout, and it seemed to be keeping him from becoming airborne once more.
Lyara's heart leapt into her throat in fear as she watched Farkas charge in. The brave and foolhardy Nord was facing a dragon god with nothing more than his Ebony sword. Lyara fired a quick succession of arrows at the giant beast's head, aiming for his eyes. He moved too quickly and her arrows bounced off the impenetrable scales instead.
She quickly flung her bow on her back so that it hung off her quiver, and released the axe at her side. She held it tightly in her right hand, its sharpened edge glinting in the light. In her left hand, she conjured some of her innate magic. Alduin was a creature of fire, and so Lyara concentrated on the cold and ice that surrounded her. What shot forth from her fingers was not the flame she had used in the dungeons with Farkas, but ice. With a hearty war cry, she charged forward.
Farkas concentrated on attacking at the rear, stabbing and chopping with his sword. The more nimble Lyara distracted Alduin with blasts of ice, and then attacked the weakened points with her axe, while avoiding his snapping jaws.
"You will die this day, Dragon." She heard Farkas taunting him.
"You are too late Alduin," Paarthurnax shouted from above them. "Never again!"
