I have wanted to try this idea for a long time since it is appealing to me.
In the future man has become extinct, instead they were replaced by humanoid creatures that acted much like them. These creatures thrust far into the realm of space but they came upon a great artifact that would bring great mystery to those aboard that science vessel. Nearby a star went super nova, the poor science ship got caught in the blast. The artifact was activated by the extreme amount of energy. This artifact brought a human from the past straight to their ship, this human looked like he came from at least WW2 but what will he do or act. Will his presence bring something worse?
