Semele is the capital city of Bacchus Moon. It is a lavish, rich and heavily populated city full of bustle and entertainment. It is home to many gambling establishments, bars, and hotels, as well as Covington Bank, which was one of the most secure and wealthy banks in the Terran Confederacy.
In 2494, Jim Raynor and Tychus Findlay attempted to rob the Covington Bank in the city under the order of Scutter O'Banon. However, the operation went awry, leading to Tychus's capture by authorities, though Raynor was able to escape.
