Lang Tanaka was a student at the Progress University in 2641. For the requirements of her studies she compiled a research about the appearance of Navigational Powers of the Pilgrims as exhibited throughout the history of space exploration, intenting to prove to the discriminating mind that these powers were not a divine gift nor inexplicable luck, but the consequence of genetic mutation engendered by non-Terran conception, gestation and birth. She insisted that Pilgrims were not a new species of being, but merely a new race of man.
