There is a light in the sky. It streaks quickly across from East to west, blue like a sapphire. It is followed by another, and another, each larger than the one before. The fourth and fifth make a dark shadow at the warriors feet as they bathe the land in blue light. The sixth can be heard tearing its way through the air overhead, and then the Orc begins to worry.
The Seventh looks as large as a melon, burning too brightly to look directly at without pain. The eighth sends the light-sensitive orc to the ground clutching at his eyes. He misses the sight of the last one passing overhead, close enough to singe the trees on either side of the plain. He fails to hear its roar as he is deafened in the first instants it is within view. But he cannot miss the impact.
The huge orb of blue fire smacks into the mountain to the west of him and sets the earth to shaking. Cracks form, trees burn, and the mountain is half the size it used to be in a matter of instants. Shards of rock from the explosion shower everywhere, setting grasses and trees aflame. If Karug wasn't already on the ground, he would have been knocked there by the tremendous shaking.
The shaking continues for a few moments that feel like hours, and dust rises into the air. When it is done, Karug takes his feet.
