Post Demon Wars
The human race was not prepaired for a war with demons so when the rift was opened between Alpha Centari and Earth and they showed up, mecha were our go to weapon. At least a decade of fighting on earth and in space went by before we finally figured out how to close the rift. We got to the rift to find the elves there examining the rift and so we meet them and they witness us close the rift with the same technology that opened it. After this long war, the calender changes in some way.
We don’t know how it started but we go to war with the elves for a while and meet the dwarves who sell to us thier technology for FTL travel. Ultimately neither the elves or humans win. At the same time, terraforming begins on planets like Mars and others in different systems.
There is more to this…
