Okay, guys. So this is my idea of how one planet engaged in this war (is it a war) came about:
Think about this theory: Panspermia
Life from another Planet 00 (working title) came to Planet 01 (working title) via asteroid/comet. From there, different species evolved and so on.
Technology in Planet 00 (working title) is mainly based on rock, implying that the asteroid/comet that crashed into Planet 01 (working title) was a vehicle, and not just some random asteroid/comet.
Planet 01 (working title) in present day is pretty much like this universe's Earth.
Organisms from Planet 00 (working title) are elvish, though vegetation there is scarce. In a nutshell, they are rock-elves.
