Professor Gwen Khan was one of the leading scientists on the Leyline Project. He has an odd personality, often speaking to himself, thinking out loud and repeating the same phrases multiple times in a row. A hyper-intellectual, his communication and personal deficiencies evidence a mentality pushed near if not into a mild form of insanity by information-overload. Khan's goal in life is to gain ultimate knowledge, which drives him to find the Galactic Leyline, a "machine-god" created by an extinct alien race that acts as a catalog for all of existence.
