Shih-huang-ti

The Shi-huang-ti was a Chinese submarine that crashed in San Francisco during the Great War. The descendants of the crew settled in the ruins of the city and became known as the Shi. The remains of this vessel were used as material to help construct the Steel Palace, and the ship's onboard supercomputer was established as the Emperor.

Appearances
The Shi-huang-ti was originally meant to appear in Fallout 2, but was eventually cut from the final version of the game, and is only mentioned by the Shi Emperor.

Behind the scenes
The name of the submarine, Shi-Huang-Ti, is an alternative Romanized spelling of "Shǐ Huángdì" (始皇帝), the first emperor of a unified China and founder of the Qin Dynasty.
