The end of the Halo story typically brings closure to the main conflicts, but leaves room for speculation and potential future storylines. It usually involves a balance of power being restored and the characters facing significant challenges and choices that shape the fate of the Halo universe.
The Halo story has ended for now. However, in the world of entertainment, things can change and there might be comebacks or related projects down the line.
Well, at the end of Halo 5 story, there's a lot going on. Cortana, who was once an ally, has now turned into a threat. The Guardians she controls are a major part of the end - they are these huge, powerful machines. Master Chief, along with his team, is left with the task of trying to stop Cortana's grand plan. It's a big shift in the story as the relationship between the Chief and Cortana, which was so important in previous installments, has completely changed. And the future of the Halo universe is left hanging in the balance as Cortana's actions could reshape the entire galaxy.
I'm not sure specifically as I haven't read this particular fanfic. But generally, it might involve the UNSC (United Nations Space Command) in the Halo universe using the Halo installations in a strategic way to bring an end to a war. Maybe they find a way to activate or control the Halo rings without causing the total destruction they are known for.
Since I haven't read the fanfic, it's hard to say for sure. But likely, there would be UNSC soldiers or commanders. Maybe the Master Chief could be one of the main characters as he is a very important figure in the Halo universe and often involved in major events related to the UNSC.
Halo 3's story is complex and engaging. It continues the saga of the Halo universe. The Covenant is still a major threat, but there are also internal power struggles within their ranks. The Master Chief is humanity's last hope. He has to navigate through a web of danger, from facing the Covenant's advanced weaponry to dealing with the mysteries of the Forerunner technology. Along the way, he discovers more about the true nature of the Halo rings and the history of the galaxy.
I think it was good. The story in Halo 4 had a good balance of action and emotion, and it expanded the Halo universe in an exciting way. The graphics and sound also added to the immersive experience.
