Alain Trottier was an superstitious, amateur scholar based in Monte Carlo. Trottier was interested in obscure topics like divination, and was married. He also knew and appreciated psychic Sophia Hapgood. In 1939, Indiana Jones used his help to acquire the Sunstone in his search for Atlantis. In order to gain his trust, Trottier asked Indy about a topic found only in the Lost Dialogue.
