the diagram at the bottom shows how Osidian and Carnelian march their forces west. Their positions in the line are shown. Taking advantage of the wind blowing from the south-west, they cover their advance with the clouds of dust the dragons raise. The rest of their forces are protected by marchin up wind of the dragons – the positions of the various contingents are shown. The diagram top right shows how Carnelian and Osidian (once Osidian has brought Heart-of-Thunder back to the centre of their line)feed their wings into the centre of the proto-crescent so that they end up at its centre at the head of two columns of dragons. The diagram top left shows the hollow crescent coming into being by advancing its ‘horns’ on either side – notebook 34 / page 12
