The Answers Are In The Stars
Nigel is a researcher from Magellan who is convinced that humans once had space-capable craft before Day-Zero. He first appeared to the party in Deadwood to discuss a salvage site they had just returned from.
Nigel’s theory is that the salvage that sometimes falls from orbit and lands in the wastes are actually pieces of a larger craft that broke apart while aloft and is falling back down piece by piece. He mapped out data and actually has a projected analysis of the locations and times certain pieces of the hypothetical craft will descend to the Wastes.
Most people consider him a crackpot but his research has drawn the attention of the Legion which all but validates his theories.
