Err...whut? The most recent continent was Dwilight, which, yes, was considered to be west of the other continents.
But the continent to open before that was, in fact, the Far East. Which, oddly enough, is considered to be east of all the rest.
Before that was the split from South Island to South-West (old) and South-East (new) Islands, and before that was Beluaterra, which, aside from the settlements on the eastern coast, had no particular indication of its location relative to other continents.
The Far East was obviously an exception.
Okay, maybe it's a crappy rule I made up. I always viewed BT as being West of the rest, though. One could say that travel between EI and FEI was rather difficult, and perhaps was only enabled by the colonization of the SEI who'd have been somewhere in-between.
