The Hyakuren is the main general purpose mobile suit used by Teiwaz and its subsidiaries such as Turbines. Teiwaz's engineer acquired the blueprints of a high output machine that was planned to be developed during the late stages of the Calamity War, and based on it, developed the Teiwaz Frame and the Hyakuren. Unlike the mobile suits used by Gjallarhorn, the Hyakuren's Ahab Reactor is from ancient times, as such it cannot be said to be a machine that was produced completely by Teiwaz. This is also partly due to the fact that Gjallarhorn has a monopoly on Ahab Reactor technology in the present day. Nevertheless, it remains an important achievement as it is the first non-Gjallarhorn MS frame completed in recent years.
Development of the Hyakuren's frame was difficult and took a long time, evidence of this is that the mass production line is not ready yet.[2] There are only 44 Hyakurens in operation as of P.D. 323, and the initial 9 machines are known as 'Single Number'. These 9 machines, of which the STH-05/AC Amida's Hyakuren is one, differ from the later machines in that they have better materials internally as well as better performance.
