-Present to 2160-ish- human expansion through space and colonisation of other worlds
-2160-2214-First interplanetary war
-2221- First contact. Aliens are in the midst of a civil war, which humans opt to avoid
-2260-2263 Human colony is attacked by accident. Human forces (Note, they have much more troops and infrastructure as opposed to aliens, though the tech is weaker) counterattack and choose a side. They gradually force the weaker army back to their homeworld and force a surrender.
-2263-2346- The shattered alien empires begin to rebuild based off the superior human economy and military. Humans rapidly become a powerful force and eventually assume full control in what becomes the Imperial Age. Xenophobic attitudes from the previous war remain and the Imperium gradually becomes a massively human-centric empire that only benefits the humans
-2346-2654- The Imperial age, of alien oppression. Realising that rebellion is possible, a newly discovered system is prepared as a fallback named Exodus, for the event humanity is pushed to lose dominance.
-2654- Earth is attacked by a new empire called the S'pher, that destroys the human army completely and pushes them out of their territory. The humans fall back to Exodus, and launch a counteroffensive in 2683 to reclaim their territory, making a multifrontal assault back into their lost systems. In 2701, they launch the final invasion of Earth and begin the event eventually called the Endgame.
Does this sound like the pacing is about rioght or should it be slowed down to roughly half the time?
Would this be feasible as a time period (In terms of pacing)
