The Order (オルダ, Oruda), full title The Code of Perfect Order to Come (来るべき完全なる秩序の法典, Kurubeki Kanzen'naru Chitsujo no Hōten), is an organization and body with the scope and power projection of a nation that is seen in Genso Suikoden Tierkreis Hoshikuzu no Shiro. It dominates the continent on which the game takes place.
Technically, we see two different versions of this Order on two different worlds. However, their differences are negligible.
Much like its more familiar counterpart, the Order of the One True Way, preaches an extreme form of predestination in which every single action of every aspect of the world had been determined in advance.
The Order began as a secret society over a century ago but only became prominent in the last twenty years. It would quickly expand across the western continent before turning its eyes on the east. Its familiar name "the Order", comes from an ancient language that the group's full name was translated to.
The Order's motive was to fuse the world with the One King's in order to bring about the Perpetual Day. This goal would lead it into conflict with the Leonos Kingdom and the Biskiel peoples among others. They were also opposed by the Star Corps, a gathering of Starbearers.
More tenacious and vicious than other incarnations, the Order cracked down severely on perceived dissent and also formulated a way to trap Renegades in a form of armor, allowing them to be utilized as nigh-unbeatable shock troops.
Despite the best efforts of its opposition, the Order would not only succeed in summoning the One King but would also see their foes defeated and their own hopes dashed as instead of being enveloped by the Perpetual Day, the world would instead become the 8th world fusion for another realm of the Infinity.
