Editing Etrahn Timeline

The following is a timeline for the world of Etrah:

'''Year 0''': Etrah is formed.

'''Year 204''': Etrah is now inhabited, thanks to divine works.  The planet's foremost population consists of humans.  The wildlife consists of many various insects, a few varieties of quadrupeds, and a few birds.  Technology is nil, and humanity lives in the wild, among the animals.

'''Year 500''': Angels visit Etrah, giving the blueprints for some basic technology, such as windmills, and boats.  This sparks a technological revolution among the Etrahn people, and the world is suddenly filled with "inventors".

'''Year 1500''': Etrahn technology now rivals that of present day Earth, and is still rapidly climbing.
