New Day Alliance
The New Day Alliance, colloquially known as the New Alliance, or most commonly just The Alliance, is a reformation of the original Alliance as created by Eieber. This iteration (technically the fourth iteration) of Eieber's Alliance began early on in the Age of the New Day, following the end of the Long Night.
The political landscape at the end of the Long Night was complicated. The first major power to emerge was the Gudersnipe Foundation, who were quick to revive the Crimson Blade and issue claims of ownership to all territories they had previously controlled.
The second major power was the Trans-Draconic Federation, who had been quietly rising in power throughout the Long Night. Backed by the collective power of several hundred dragon flights supported by trillions of human subjects, the Federation was clearly a force to be reckoned with.
The third major entity to emerge (and the first real multi-world government of the ND era) was the Earth-Sphere Confederation. While claiming to be a "spiritual successor" to the original Alliance, this group was largely devoted to protecting the interests of autocratic member-worlds who had seized power after the end of the Long Night. Confederate member worlds were bound together more by their desire to maintain the status quo than any real unity, and were easily disrupted. The Confederacy ended about a decade before the reformation of the Alliance.
In the early decades of the era, the Trans-Draconic Federation was quick to form close ties with the Gudersnipe Foundation. Throughout the Long Night, the Foundation had not been permitted to issue currency as they had during the old Alliance era. As such, they emerged from under the thumb of Samuel Fate signficiantly lacking in financial resources. The dragons, meanwhile, had continued to run a successful banking system under the empire, and were on hand to produce a universal currency system; but the TDF lacked economical and technical skills needed to quickly re-industrialize. The partnership was very obvious, and mutually advantageous to both sides.
In general, the goals of the TDF were mostly compatible with those of the Gudersnipe Foundation. Both sides were intent on creating long-term stability in the regions they controlled, and both maintained generally similar values. The Foundation, in principle, objected to the dragons' use of human "slaves"; but this was largely an issue of semantics. Life under draconic rule was, at at least the start of the era, better than it was for the struggling Foundation. Further, the dragons had a very loose definition of the term, and generally accepted that anyone not willing to live under their rule was allowed to leave. Often times, former slaves would even be gifted with goods and silver to help them start a new life. This practice ended at the start of the New Day, but as the dragon's human subjects moved into an industrialized society and the standard of living continued to improve, there were few who objected to their status.
The TDF helped the Foundation to stabilize while the Foundation provided technology and helped to train skilled laborers to the TDF. Meanwhile, the Confederacy worked out means of partially restoring ships and weapons left behind by Samuel Fate. While they lagged far behind the other major powers in technology and manufacturing capacity, this gave them an enormous advantage militarily.
Despite differing interests, the Confederacy still required economic ties to the Foundation and Trans-Draconic Federation. The downfall of the Confederacy came when an error in their electronic money system suddenly made their currency worthless. Massive amounts of assets were purchased by the Foundation and TDF, and this effectively collapsed the Confederacy without firing a shot.
The New Day Alliance solidified under Conri Jason Jusenkyou and a new Order of Slayer Dragons. While many former confederate worlds attempted to maintain a strong identity, by and large they were absorbed into the Alliance, and required to follow Alliance laws.
At the end of Conri's life, the remaining Slayer Dragons decided that, barring the return of the Pendragon's sword, the Order would not name a new Pendragon. The office of Light Bearer was created to hold the Pendragon's Slayer Dragon power, the order continued. Little of note happened for the next four centuries, except that towards the end of the fourth century ND, the surviving descendants of the Long Night's wealthy landowners began a plot to rebuild the confederacy.
