J.R.R. Tolkien

It's my opinion that J.R.R. Tolkien was perhaps the greatest fantasy world builder.  He created a vivid world with languages, races, flora, fauna, geography and weather all worked out over a history spanning thousands of years.

 Welcome to Middle Earth includes maps and language information for the world he created.

The One Ring/Tolkien Online: Claims to be the ultimate Lord of the Rings site I don't know, because it takes so long to load on my machine that I'm out of time before I can explore.  Looks good, anyway.
