Delta Orsea System
The home system of the Trevan Alliance, a member nation of the Hyperion Federation. The Delta Orsea sysetm is a binary star system.
The class G star is named Delta Orsea A and the class B star is named Delta Orsea B.
The Delta Orsea system is a binary system between a class G star and a very bright class B star. The trevan homeworld, Sinus, orbits the class G star and is the 3rd world from the star. It is very possible to see Delta Orsea B (the class B star) from Sinus with the naked eye, sometimes even at day. Of course, the trevans have defended the system effectively, placing large numbers of defence platforms in various orbits in case an enemy would somehow end up this deep in HF territory. They also exploit the system for resources, for example, star lifting both the stars and mining the many worlds located here.
The Trevan Alliance would explore their home system, Delta Orsea A, before exploring Delta Orsea B. After their nuclear war and re-introduction to space travel, they would recolonise several worlds nearby. Only one colony seemed to have survived, but the fact that one colony survived was amazing to the discoverers. The culture of that world was so different it was almost alien to them - and their language drifted enough to become near unrecognisable to the original Sinus society, but they successfully established contact with them. Both sides had a war which ended in a decisive Trevan Alliance victory, and they reclaimed their long lost colony.
After Delta Orsea A was colonised, the obvious next step was to colonise Delta Orsea B. They have yet to make contact with any alien species at this point, but used their highly powerful orion drives to reach this new system. This method of travel would take a ship to relativistic speeds so the Delta Orsea B colony was set up quite fast. As the trevans themselves would not withstand the extreme acceleration of the orion drive detonating, they were placed in cryopods for the duration of the trip. This measure continued until the Trevan Alliance developed FTL which was well after both star systems were fully colonised.
The Delta Orsea system was defended with a very large number of nuclear weapons in the Trevan early history. This is because of the Trevan's inclination towards nuclear weapons despite the significant negative impact these weapons have. These fortifications were nearly unbreakable by any other faction due to the sheer number of nukes, which made the Delta Orsea system an extremely powerful fortress in its own right. However, they had an issue where the Trevan Alliance almost entirely depleted all uranium sources of their system, which was a problem until they invented fusion warheads that were even more destructive and required only hydrogen to construct. Due to the extreme brightness of the Delta Orsea B star, they would use it to generate a lot of power through solar energy. They have not built a Dyson Sphere, but are star lifting the star, providing the Trevan Alliance with a lot of materials to construct starships with. They had one final war before making first contact with the HF and, eventually, joining it for protection. The various conventional weapons of the HF proven to be far more effective than any Trevan nukes, the Alliance soon phased them out - but they remain advanced in nuclear reaction technologies, such as the Transmutation Reactor.
