Nigel Sheldon is one of the co-inventors of the wormhole technology and co-owners of CST, and hence one of the two most wealthy and powerful people in the Commonwealth (and thus, all of human history). He is head of the Sheldon Dynasty. For the first few hundred years of his life he lived a hedonistic but debauched lifestyle, having a harem of wives for example, whereas in later life (he lived to be over 1,000 years old) he became monogamous.
During the Commonwealth Saga Edit
Nigel was one of the key figures who participated in the Starflyer War. While initially a sceptic (like almost everyone else) he was instrumental in defeating the Prime threat as well as the Starflyer itself.
During the Chronicle of the Fallers Edit
As the most powerful human alive, Nigel is approached by the Raiel to infiltrate the Void and gain intelligence from Makkakthran, the only Raiel starship known to have survived the Raiel invasion of the Void 1,000,000 years ago. However Nigel already has plans to lead a colonisation fleet outside the Commonwealth, and outside the galaxy, to found a new civilisation. This, and the very low chance of surviving an attempt to infiltrate the Void, combined with an insatiable thirst for knowledge and adventure, leads him to create a clone of himself, who will attempt the infiltration.
