Factory (Super Mario RPG: Legend of the Seven Stars)

The Factory (also known as Smithy Factory and called Gate on the overworld map) is the gloomy dimension where Smithy and his cohorts resided in Super Mario RPG: Legend of the Seven Stars. The entire factory is filled with Smithy's Machine Made weapons and the assembly lines that carry them. The factory's design greatly resembles the Airships of Super Mario Bros. 3, including the Bolt Lifts sometimes utilized to reach far platforms and the fog that fills the air. Smithy Factory also refers to the seventh and final mandatory world, which includes the Smithy Gang-occupied Bowser's Keep, Vista Hill, and the Factory itself. It is considered World 8 in the Shogakukan guide and World 7 in the Player's Guide.

Underground Interior
After defeating a Machine Made Yaridovich, a brick explodes to open a passage deeper underground. This leads Mario and company directly to a boss battle against Cloaker and Domino and their pet snake (either Mad Adder or Earth Link, depending on which of the bosses is left standing).

The inner part of the factory is seemingly made of all steel. To the right, in each room, Mario can witness the process of a Jabit being manufactured. According to a Shyster, the foundations for the floor Smithy was operating on had only been applied the day prior to Mario and his party's arrival.

Trivia

 * The music has an unusual time signature of 13/8 (13 quavers [eighth notes] to a bar [measure]).
 * The Factory is actually referred on the world map as "Gate", but it is called "Factory" on the save point.
 * Despite the management staff consisting of four boss fights, only Gunyolk and the Factory Chief have boss music. The Clerk, Manager, and Director have regular enemy music. Additionally, the Gunyolk is the only one of these with the "fading out" effect most bosses have upon defeat, with the rest having the "popping" effect usually reserved for normal enemies, together suggesting the game considers them as such. The players statistics are restored after each of these fights, however, which normally only happens for bosses.
