The Babylon Project

The J/Lai were an offshoot of the Brakiri race that once inhabited Theta Omega II.

In August of 2256, Anna Sheridan took part in an IPX sponsored dig on Theta Omega II, where they found an artifact that would later be found to be a biomechanical device.[1]


Seeing as the biomechanical device found on their homeworld was Shadow technology, sounds plausible the J/Lai were involved in a Shadow War. Such may also be the cause for their extinction.
