Embers of Empires
The Makers are a precursor race that once filled the galaxy. They left long before the Saldrallans and Templars began their Thousand Year War. Remnants of the Makers have long ago been plundered and fought over. New sites are occasionally discovered, but it’s been decades since the last one.
Maker technology forms the basis of modern tech. They engineered the first jump gates and bred the first bio-ships, they brought countless races into the vastness of space. On many planets they are revered as gods.
No one knows why they left, or where they went.
