Don't know where to begin?

While ultimately it doesn't matter which arc you begin with, Cecil arc is recommended if you want my recommendation.

And then Masu arc + Shattered union arc. 

Feel free to visit the lore section as well which holds stories of its own.

Shattered union arc (12)

If you want a central plot to follow, this is the arc you should start with.

This arc deals with the general political situation in Sol system from A.D. 9599 to 9670.

This arc is completed.

[Shattered union arc] [1] [Revolts] [9599]

This story was the first one as Two Clusters.

I had numerous stories prior this but they weren’t officially under Two Clusters.

[Shattered union arc] [2] [Karin Bau] [9603]

Something to note. When this story was written back in 90s, I, for some reason, believed that planet Saturn was a barren planet. When I eventually found out that Saturn was actually a gas planet, it was years later and it was already too late. Numerous stories and lore were created for the planet to just erase the whole thing.

Therefore, Saturn in Two Clusters universe is a barren planet.

[Shattered union arc] [9] [Regression] [9641]

[Hermit arc] [3] [Moon refugees] [9637] is a recommended story prior reading this one.

United Solar system Federation, or United Sol in short, is deteriorating quickly without any signs of recovery.

[Shattered union arc] [10] [Cheap pride] [9648]

Fraser tries to push his own agenda for once.

[Shattered union arc] [11] [Darker than black] [9662]

The end is nigh for United Sol.

[Shattered union arc] [12] [Shattered union] [9670]

This story concludes this arc.

United Sol is finally done for. Good riddance, I will say.

This story has a long history with me. I wrote the basic part of this story a decade ago, but due to its previous stories not being completed, it never had a chance to shine, until now.
