In the novel I am writing one of the twists is that story actually takes place on a distant earth except it’s unrecognisable due to it being permanently altered by a long series of devastating wars .
Now part of this is that the location and shape of the continents have been changed, some have been erased from existence and others shattered (example India has been separated from Asia becoming an island) . My question is how would it be possible to move or destroy a continent?
