History
Testing the Hammer of Dawn
In the last year of the Pendulum Wars, when the Hammer of Dawn was tested at the Garadaner Test Ranges, Gen. Bardry Salaman ordered KR Seven-Three to fly over the test zone and report what it saw. Its pilot reported that the Hammer of Dawn had destroyed everything there and created a large hole, and remarked that he couldn't wait to see the Indies faces when they used it on them.[3]
