Nubar Kamalian is a Gateway Prospector. He had been out 5 times, nearly killed twice.

Once he landed on one Diedre-class planet, fought his way through giant cockroaches and recovered a box of Heechee disks. He was awarded $50000.

The Gateway Corporation believed the disks are worthless by-product of industrial process but himself didn't believe so. He used to wear on of those disks as a medallion.

He met the player in the Blue Hell bar and challenged him to a game of trivia. He then awarded him with his medallion.
