How "old" are the kingdoms per-say? Have there been others at one point? What other celestial bodies are within Remnants solar system (asteroids, planets, dwarfs, stars, constellations)? What was techongoly like during the Great War and Human/Faunus War. Was it like the tech used in World War I and the Cold War?

...and I just realized that the answers might provide spoilers. :/
