Prologue
It has been 400 years since Eragon left Alagaesia to rebuild the order of the Riders, which he did in earnest. The eggs hatched at a ferocious rate, for riders of all different races. However, for whatever reason, Eragon has not returned, nor have any of the Riders that were sent there to be trained by their mysterious leader. And now a newthreat looms, though not entirely new to some...
Eragon stood on the balcony of his room, which jutted out of the top of the towering mountain. Displayed below him was the new world he, with the help of his elven companions, had created. Buildings of a brilliant, shining, white marble dominated the entirety of the mountain. From the quarters he shared with Saphira, he could see the entirety of this new city via their 360-degree balcony, which wrapped around the top of the mountain. Though the number of buildings below him were numerous, the only inhabitants of this great city, Gedwey Istalri (Shining Star), were dragons and Riders.
Thousands of dragons dominated the sky and mountain, though only a small portion of those dragons were bonded to riders. Of Riders in full, They're numbered about 300, with about 800 still in training. The next class of Riders would not be named for another 50 years. Eragon was very thorough in his training of Riders; he wanted to make sure they would be ready for every possibility they would ever face. He wanted them to be the best and fiercest warriors in the land, but also the wisest, gentlest, and most knowledgeable.
With the allotment of different races, it was an enormous task, but he also learned much from his students, which was what he enjoyed the most. The first segment of a Rider's training was that they learn each language spoken on the island: human, Urgal, elvish, dwarvish, and even the dragons mental language of sounds, images, smells, and feelings. This greatly reduced the number of incidents that happened with the members of different races from the outset.
The most controversial rule of Eragon's was his Abolishment of Heritage rule. Once one came to Gedwey Istalri, they were to strip themselves of any allegiance to their clans, houses, or groups of any sort they had back in Alagaesia. They were now Riders, and that was all that mattered.
He didn't strip them of their race, however. Eragon obviously realized there were genetic differences in each of the four races. From an early time in their training, he had his four elders collaborate to put divide the riders into "quads" by the time they became Riders in full. A quad consisted of one Urgal rider, one elven rider, one human rider, and one dwarven rider. These were the teams that would take on missions together, depending on its magnitude. There was only one quad larger than four, and it was Eragon's own quad, which consisted of him plus his four elders; one of each race. The elders were Bolstag, a male Urgal, Dorjax, a male dwarf, Vidya, a female elf, and Murtagh, who had arrived at the home of the Riders 200 years prior. Never in the history of the new order had their been any reason for the Riders to go to war as a whole entity, but if they did, that would be the only time the Riders would be divided by race into four different battalions, each commanded by their respective elder, all falling under the supreme command of the lead Rider.
Eragon's methods turned out to be a very effective tool for uniting the Riders under a single banner, without any quarreling amongst themselves. It was quite obvious that a civil war between the Riders could never be allowed to happen again.
So Eragon and his riders have stayed in Gedwey Istalri since the end of the rebellion to overthrow Galbatorix, occasionally sending quads into Alagaesia to settle smaller matters, with Queen Arya of the elves being though only permanent Rider in Alagaesia. Though something is brewing that may require the attention of quite a bit more than a queen or even a quad…
