Even the humble mopani worm is pressed into service to illustrate one of Magda's own asterisms
The shifting position with respect to the stellar background of the sun at this time, as it reached its southern horizontal extremes towards the winter solstice of mid-to-late December, would have been detectable indirectly by careful attention to helical risings and settings of the region's stars--or indeed, if such could be imagined, to the changing positions of other stars or asterisms

5 degrees further west from the asterism
is the globular cluster NGC 6352, situated inside the diffuse emission nebula GN 17.

Here, the correlative cosmology of the "Fire Phases" (wuxing) is invoked to explain the antagonism between Chen and Chu, based on their archaic astrological linkage with watery and fiery asterisms
Searching for asterisms
