Halo-Star War Crossover
Title: Back to War
Rate: M, to be safe as there will be cussing and actions.
Disclaimers: I do not own Halo or Star War. Halo is own by Microsoft, Bungie, and 343. Star War is own by George Lucas and BioWare. Oh yeah, and there will be few elements from Halo War, so I do not own Halo War as Halo War is own by Ensemble Studio and Microsoft. I do not own Starcraft as Starcrafts are own by Blizzard. Yes, there will be very few elements from Starcraft such as Yamoto Cannon and others, but in sense of similarity. Honestly, I'm not making this story for profit, just for fun.
Warning: My grammar is shamefully suck, so please bear with me.
Summary: Since the end of Clone War and end of the Republic as well as birth of Galactic Empire aka Imperial with Darth Sideous being emperor, Darth Sideous decided to expand the power of Imperial and sent couple Venator-class ships to explore far out of outer rim. By dumb luck, a group of Venator-class ships found the Omega Halo ring, the last of Halo rings. While the Imperial ships were investigating the Omega Halo, two different groups of ships appeared, one from the UHS and other from the CAS. At first, the UHS and the CAS ships sent several transmissions and warnings. However, the leading ship of Imperial group ordered his group to attack both the UHS and CAS ships. His order backfired as both factions fired back and nearly wipe all the Imperial ships…The war between the power-hungry Galactic Empire and two factions, the United Human System and the Confederation of Allied Species have begun..

History of UEG and UNSC, now called UHSG and USMA
It took several weeks to end the Human-Covenant War, a war between the human-Sangheili and the Covenants with the Brutes retreating back to where ever they came from, the Jackels going back to their old days of piracy, the Grunts joining the Sangheili along with the Hunters and the Engineers. As for the Prophets and the Drones, they were never seen again.
Now, the Great War was finally over, the mankind cheered and grieved as a rather huge percentage of human population has been killed, along with more than several colony planets have been glassed by the now-dead Covenant.
It took more than 25 years to get the UEG and UNSC back to their full strength as they were, before the Great War occurred. However, despite that the Covenant is no more, the UNSC still facing the threat from rebels, but different rebels from the Insurrection. Unlike the Insurrections, the rebels want the UNSC to give the power back to the government and bring back the democracy. The UNSC insisted that the mankind is not back at full strength. Then once again, the mankind has gone into another civil war for 7 years. Seven years later, the UEG and the UNSC have been burn down and from their ashes, the new-born government rise. The United Human System Government, or the UHSG for short, along with its military, the United System Military Arms, or the USMA for short.
In UHSG Senate, each planet will have its own Senators and the President can be elected as leader of UHS and USMA. To be qualified for President, person must be in Senate for 10 years minimum, have experience in politic and have people skills, and must be 45 or over. The President will have two terms maximum with 3 years per term. That's total of 6 years for President.
As for the former Covenants, the Sangheili have formed new empire, the Confederation of Allied Species, or the CAS for short. Along with the Sangheili, the CAS is joined by the Grunts now called the Ungoyys, the Hunters now called the Mgalekgolo, and the Engineers now called the Huragoks. The CAS government is called High Council of Confederate with Chancellor being the leader of the CAS.
Although there's no longer a war between the humans and the non-humans, the tensions still existed between them, similar to old day of Cold War between the old United States and the old Soviet Union. Almost a month, after the Great War, both factions: humans and the aliens have signed the agreement called the Great Promise.
The Great Promise stated that the humans will not attack the Sangheili, the Ungoyys, the Mgalekgolo, and the Huragoks (for some reason that the Huraogks have been included in conditions). The Sangheili and other races will not attack the humans. Both factions have agreed to work together as to fight the now called the Brute Remnants, the Jackel Pirates, and the remaining Floods. They also agreed to find the remaining Halo rings and destroyed them. Before destroying the Halo ring, both faction must be there as sign of "trust" as to make sure that the Floods don't escape their prison.
When the UHSG and the USMA have been formed, the Great Promise have been renew, with same conditions, but few more things. The UHS and the CAS have agreed to shared their cultures and technology, much to the populations' protests as both the UHS and the CAS people do not want to do anything with each other. Though, both faction have gained something from the Great Promise II.
Almost 125 years later
The tension between the UHS and the CAS has lessened, somewhat and the war against the Brute Remnants and the Jackal Pirate was over with the Brutes being bombed back to their Stone Age and the Jackals have joined the CAS, much to outrage of the UHS and the CAS citizens. Both factions have imporved in term of technology and economy. Unfortunately, they still have yet to find the location of last Halo ring, the Omega Halo.
Several months later
The USMA and the CAS Navy fleets have finally found the Omega Halo, but they have encountered a group of pointy ships who have already found the Omega Halo and were about to get closer to the Omega Halo. Not wanting the Floods to escape, the leading captains of USMA and CAS both send transmissions and warning to the newcomers. During the transmission, the USMA and the CAS were surprised to see that the new-comers were actually humans and from faction called the Galactic Empire, or the Imperials. The same can be said for the Imperial "scouting" group of Venator-class ships. Sadly, the First Contact with the Imperials has gone sour. After receiving the message from the Emperor, the Imperial group continue their course toward the last Halo. Both the USMA and the CAS ships have attempted to intercept the Imperial ships, but the Imperial ships have fire the lasers at the USMA and the CAS ships, thinking that these ships are primative compared to "elegant" designed ships of the Imperial.
After the first shot, both USMA and CAS ships have fired back, much to the leading Imperial captain's surprise when lasers didn't do much damage as thoughted by the Imperial and that both USMA and CAS ships wiped out two-third of Imperial "scouting" group.
Week later
The UHS and the CAS have sent their diplomats to the supposedly the capital of the Imperial, according to leading Imperial captain during the transmission. The diplomats were never heard again as they may have been killed by the Imperial. At the same time, the Imperial has launched attack on one of the CAS colony planets called Gradeglo, populated by Sangheili and the Mgalekgolo.
Angered, both the UHS and the CAS have declared war on the Galactic Empire, or Imperials. Both factions have also agreed to hold temporarily truce as they have common enemy. Since then, they have been getting ready for the war, increasing recruitments, stepping up the technology research and improvement, and others.
This war will have huge impact on the UHS-CAS and the Imperials.
Who will win? The Galactic Empire, who looking for more resources. Or the USMA-CAS, who have declared war on the Galactic Empire for "unprovoked" attacks.
Author: Well, this is pretty much a brief history of what happen to old UNSC and the former Covenant alien. The UEG and the UNSC have been replaced by the UHSG and the USMA. While the CAS consisted of the Sangheili, the Ungoyys, the Mgalekgolo, the Huroguks, and the Kig-Yars.
