Freedom From Two Eras (Cancelled)

Things hasn't been so good for this Earth-like planet.
First, an expansionist empire ravaged the whole world thousands of years ago and disappeared but not for long.
Second, they only have a dozen years till this Empire returns and ravage the world again.

Things have been going good for the inhabitants up until the number 1 superpower, The Holy Mirishial Empire's emperor was assassinated by a militia supported by the remnants of the expansionist empire from long ago. HME, along with the Annonrial Empire, turned against the whole world and put them on the edge of losing.

Unbeknownst to them, two countries of identical names and principles that came from different eras appeared out of nowhere. This may or may not turned the tide of the war in favor of the Coalition against HME and AE.
