In 2268, Aaraka boarded the USS Enterprise, bound for an Interstellar Geophysical Conference on Beta Aurigae. While aboard the Enterprise, Aaraka had several intense encounters with one of the other delegates, Professor Patrick Moore.
A few days later, Moore was found dead in his quarters, and although it was found that Moore had suffered a coronary, his manuscripts were stolen, and Aaraka was one of the primary suspects. The killer was later revealed to be Moore's technical assistant, William Terrens. (TOS comic: "Sweet Smell of Evil")
