Alrighty, as promised, a short explanation for universes across my stories.

  First of all, the vast majority of my stories exist in the same multiverse. The Fallen World, Manaforged Robotics, The Dragon Imperium (that one is only on patreon, I burned out on it extremely hard). The only exception is The Eternal Seeker Saga, that is entirely separate.

  For simplicity's sake I usually call it my 'general multiverse'. The stories and universes within share the same multiversal wide principles and rules, though those haven't been expanded upon much (yet), outside of the Dragon Imperium.

  Earths in my multiverse tend to share some key characters and events. Arcadia, for example, is one of them. Something happening to Europa and Pluto is also a common (but not mandatory) occurrence. Though it wasn't supposed to start that way, The Fallen World being my story with the most lore and character development meant its version of Earth has more or less become the 'gold standard', so to speak.

  You might be reading a stolen copy. Visit Royal Road for the authentic version.

  Sapphiria's Earth, for example, is extremely similar to Alexandra's, until they began diverging quite significantly after the Interplanetary Wars, as the development of artificial gravity failed to materialize due to different physical principles, driving both universes apart on very different paths due to technological differences. For example, the lack of artificial gravity meant the grav-drive could not be developped. This meant no reactionless propulsion, and the continued (not to mention ever increasing) need for reaction mass for space travel lead to Jupiter and its moons being further developped and invested into even during the interstellar age, avoiding their half abandonment and neglect during The Fallen World's 22nd century. This lead the fate of Europa (and Ghost, its Butcher) along a considerably different path.

  One thing that I feel worth noting however : ONLY Earths and associated stellar formations (the milky way and andromeda, but NOT their contents, which vary) repeat across the multiverse. There is one and only one Alcheryos, there is one Halcyon, ect. Why ? Spoilers is all I will say.

  If you have any questions, leave a comment, and I'll do my best to answer them (and maybe add them to the file itself) !
