Humans have achieved the seemingly impossible - faster than light travel.
Despite discovering hundreds and hundreds of planets that once contained intelligent life, not a single planet has been found where that life still remains. All these planets have one thing in common - the civilizations have been wiped out, either by accident or by design.
Linda is an Astroarchaeologist and her job is to find these dead civilizations and learn from them, so humans avoid the same fate.

Jemm-r is a time traveller, part of a group whose mission is to reduce human suffering.
Common belief is that any small changes in history would adhere to the Chaos theory, with massive differences down the line.
The actual mathematics behind it show this is not the case. Incredibly, a few hundred years later, almost no difference appears in the timelines. With this knowledge, Jemm-r's team''s mission is to travel in time and do minimal alterations to reduce human suffering throughout history. It is a truly noble profession.
Or is it?
