The dragon struggled against the ice, roaring in anger at Sabine. Do'rhajul and Yerig had recovered by this point, but they were keeping their distance from the trapped beast. Yerig was at the dragon's right, holding up his blade, while Do'rhajul circled around to its flank. 

Regardless of whether or not the dragon now understood how the staff worked, he certainly understood that Sabine was no normal mage. She was stronger than he had assumed, and he was paying the price for underestimating her. He tried in vain to struggle free from the ice once more, then stared her down with a low growl.  "You...are not Dovahkiin. Am I to be slain by my bait? Orin brit ro. Do it! I will not surrender to a joor!"

It seemed the dragon did not intend to give Sabine a choice in the matter, as he raised up his head and let out another shout to the sky. [i]"Strun-Bah-Qo"[/i]

Within seconds, the dragon showed the true potential that the Thu'um held. Thick rain clouds suddenly materialized in the sky in what had been a sunny day. A downpour of rain fell from the sky, and they could hear the roar of thunder above. 

"Lightning!" Yerig shouted from behind the dragon to warn the others.
