Fundamental to my tales of Izan is the existence of two gates from
our world to that of Exura. One-way gates; there is no returning for
those who travel to that other world. Nor can one use them anymore.
The wizard Hurasu blocked both in what would be the mid-1930s here
and only an exceptionally powerful magician would be able to force
his bindings. None such exist in our world.
These two gates are
somewhat opposite poles in both worlds. In ours, one exists in the
southern Ural Mountains and and the other in the South Pacific. Their
approximate locations are 55N and 60E for the Ural Gate, and 120W and
35S for the Pacific Gate. These have remained essentially stationary
over millions of years though, as the magnetic poles, they might
meander just a little.
But the continents
and oceans would themselves have shifted. The Pacific Ocean is
somewhat of a constant, and at least for the last 250 million years
the Pacific Gate has been located in it or its predecessor, the
Panthallasic Ocean, which formed some 750 million years ago. We
needn’t concern ourselves with anything earlier than that, I
suspect.
This does mean the
Pacific Gate was in the ocean when the last Mosasaur lived. It is
likely the Itza encountered in a couple of my stories is a descendant
of that aquatic reptile. The Ural Gate has generally been on land
during that same period though shallow seas may have engulfed it for
periods.
Exura would have had
its own extinction events, some unique, some paralleling those of
Earth. The dinosaur-killing asteroid did not occur but there would
certainly have been similar events. Perhaps there are in all worlds,
even those of the gods. This is one reason creatures extinct in our
world persist in Exura, though generally not in large numbers.
Evolution goes on there too, but not necessarily at the same pace as
on Earth.
Of course, the Exura
continents would also have drifted. The gates there are a subject to
take up another day. We can say that, in addition to the gates from
Earth, there are quite a few going to and from other worlds. That is
one factor in the ease of using magic there in comparison to Earth,
which is practically without sorcery of any sort. Some worlds, such
as Hirstel or some of the homes of the various gods, are even more
connected.
Does Earth have any
other gates to or from one of the infinite worlds? We have mentioned
one that opens in Anatolia, one-way only from Atlantis. Hurasu came
through it and was stranded here until he found the way to Exura. A
few others have passed to our world and some may have never have
discovered an exit. There may be a few hidden ways here and there,
difficult of passage or leading to inhospitable — or even deadly —
worlds. Perhaps we’ll discover one or another of them in a future
tale.
