The Interstellar Marshals Convention was a convention of Terran Confederacy marshals that met at bars and hotels, gathering law enforcement officers from across the Koprulu Sector. In 2494, they met in the Blue Note, a bar in the Rapture Hotel and Casino in the city of Semele.
Jim Raynor and Tychus Findlay met their contact Jennifer at the bar before their heist on Covington Bank, not knowing the convention was going on at the same place. However, they found Marshal Wilkes Butler and Deputy Rett Coolidge in attendance, who recognized them. The two were forced to escape the bar and lose the marshal's persuit.
