Well im unsure how the Triarii will get put back on there homeworld(Aetherii perhaps?). I was going to say that the computer development went a different direction rather then language, so there being different coding and processors and such, making it hard to decode the old technology. As for how I plan to keep English with the Equestrians and Humans Faust gives it to both, and has placed them closer together this time around so she can see a strong Human-Equestrian Alliance early on, And as for space tech she plans to push inventors and scientists in the right direction untill both the Equestrians and Humans have FTL drives, from which point she won't help them(Triarii will still get to space slighty before the Humans and Equestrians though).
