Rekarian
The Rekarian home world of Rekar III is in the Trinity Sector of space.
History
A very long time ago, during the original migration of what would become the Romulan race to their new homeworld, one of the ships became separated from the rest due to mechanical problems caused by a strange spacial abnomalie. These problems caused them to drift far off course. Their communications system was to badly damaged to repair.
Finally they were forced to make a landing on the closest Class M planet they could reach. This landing was on Rekar III. They crashed onto the surface of the planet. In the aftermath of the crash they lost 16% of their people due to various factors. They might have lost a lot more if the natives had not been able to overcome their fears and seeing these strange people were in trouble came to their aid.
This aid included medicine, food and help building shelters and planting their first crops. From the very start both races seemed to find aspects in the other that fostered a true friendship. This peaceful initial meeting blossomed into full cooperative contact with technology, skills and food sources being freely traded back and forth.
It was not long before this contact resulted in intermarrage between the two races. Now after so many years their is no longer two races, only one.
