— Thomas Kyangu on Valhalla
He grew up in Melbourne, Australia and had a thick accent. His mother was Martu and his father European. He went to college in Perth and spent some time in America, before moving to Melbourne and marrying a woman called Hannah, who died of cancer when she was only twenty-three.
He had discovered a cave painting in Datum Jigalong when he was a boy, during one visit to his grandparents. After Step Day, he returned to the site and stepped to Jigalong West 10. Here, there was another cave painting, similar to the one on Datum Earth. He deducted that it must have been put there by an Aboriginal natural stepper, thousands of years ago.
After Step Day he became a comber and lived in Valhalla - he had a part in the concept design of the city. He was interested in the question of how human civilisation would be shaped by the Long Earth, and so wrote a book about the combers and traveled the worlds to give talks about the subject.
He is described as being around fifty, having long black hair pinned back in a ponytail and a dark, reasonably handsome face.
