Legend has it that there was a time in blackfellow land when the night came down like a black cloud and veiled the world in darkness letting neither moon nor stars be seen. But as Bohra liked to feed at night, he objected to this darkness. Being a great wirinun, he put an end to it by just rolling the darkness back as if it had been a rug and let it rest on the edge of the world while the stars and moon shone out. 
Bohra was very pleased with himself as he could now see to feed during the night and he could go about as he pleased on his four legs, for in those days Bohra went on all fours like a dog. One night as he was feeding, Bohra saw a number of fires ahead and heard sounds of many voices singing. As he got closer, he saw strangely marked figures dancing round and round the firelit circle. The voices grew louder and louder as the boomerangs clicked faster and faster and then the noise died away into silence
