The mighty Lich King Arthas was sent flying like a baseball by Zul'ra's Dragon Tail, smashing into the rock face of a nearby ridge. When he fell back down, two patches of snow shaken loose from the cliff covered him.
"Heh heh!" Zul'ra grinned at Arthas, buried beneath the snow that had fallen from the rock wall, baring his sinister fangs as he prepared to rush over and kick him while he was down. But before he could move, several sharp whistles suddenly tore through the air beside him.
Following the sound, Zul'ra looked up and saw rockets trailing fiery clouds as they rose from the northern mountains. Startled, he abandoned any thought of dealing with Arthas, broke into a sprint on all fours along the ridge, spread his wings, and dove off the cliff.
