So If Time-Travelling Space Lizards Invaded In The Time Of Guy Fawkes And Dimensionally Displaced Humanity And Claimed The Earth As Their Own...

No, seriously this is the kind of thing I spend my days thinking about.


So give us another thousand years or so to get some decent laser guns and semi-working spaceships. We can flounce around our own solar system like it's anyone's business, but we're still not up for interstellar travel.


But the Ankiolum are. They're this race of green, lizard men, who have a bit of a handle on time-travel and time-related technology. They send satellites across the galaxy looking for planets with a 'temporal weak point' literally a place in the universe where time is a little looser and more malleable. 


Turns out there's a temporal weak point on Earth. So the Ankiolum launch a full-scale invasion. We try to be diplomatic and eventually put up a fight, but are vastly outmatched in terms of technology.


The temporal weak point is tiny, so the Ankiolum can only send one person at it. Said person winds up in 1605. From there he has to set up camp beneath the Houses of Parliament and use some kit to widen the temporal weak point and allow through the invasion force.


Guy Fawkes sniffs him out and so decides to blow up Parliament and do away with the nasty invader. Well instead, history plays out as we know and Mr. Fawkes is arrested before he can light the fuse of all his lovely gunpowder. 


A few years later, the temporal weak point is wide enough and the rest of the Ankiolum come on through. They're not entirely monstrous so as opposed to wiping out Humanity, they set up some space-colonies and displace us to there using some clever, planet-wide dimensional technology.


Now as a side effect of the dimensional displacement, all of Humanity gets a little scrambled. As far as we're aware, we've always lived in space. We evolved in space.


From there, the Ankiolum have got a nice habitable and more importantly empty planet to colonise.


That's not to say that all hope is lost. You don't just have the course of history altered with zero side-effects. There are some people who know that something just isn't right with the universe and some who are intuitive enough to know to Earth was once ours... somehow.


And then there are those people, maybe only one or two in the whole Human race, who know EXACTLY how things are meant to be. They remember both time-lines.


But really, it's just our word against theirs. Who's ever going to believe us...?
