What happened to the sleeper ships?-answer
Kusari:
As the Kusari sleeper ship approached the Sirius sector, they looked for evidence of high percentages of water, analyzing spectrographic wavelengths of various planet atmospheres. One area in particular looked interesting. Lying near a distinctively shaped blue nebula that the on-board astronomer named the Crow, it was composed of relatively young stars, and possessed at least two planets with high amounts of atmospheric water vapor and oxygen. Planetfall was made on the New Tokyo in 5 AS., five years after the arrival of the Liberty. New Tokyo had plenty of water. What it didn’t offer was much land. The ocean planet was dotted with a few small volcanic islands. A culture that had left their cramped homeland far behind had to accept a cruel twist of fate once again, on the other side of the universe.
So,the Kusari was sank under the sea.
Bretonia:
The Bretonia was one of the last sleeper ships to arrive in the Sirius Sector, almost twenty years after the Liberty, Kusari, and Rheinland had made planetfall on what became their respective homeworlds. In the chaos of Exodus, the starboard engine array of the Bretonia was destroyed, requiring her to limp the rest of the way to Sirius.
It sould be in some where on plant new Lodon,the area was no use.
Rheinland:
The Rheinland was among the second wave of sleeper ships to arrive in the Sirius Sector, along with the Kusari. The Rheinland eventually elected to make planet-fall in an area of Sirius close to the Walker Nebula and with easy access to the resources required to rebuild the Rheinland nation.
I stall not know about why...
