This is a topic that I feel I must answer to, because I'm mainly involved in the game's text writing.
The Empire's name is as unique as a finger print or a DNA.
In fact, the Nomad Invasion participants who had spent some time reading my AARs might find this name in some of them.
As for the rest of the names, like my boss said, there are many fantasy stories that use similar names.
And they are so many that they have already been carved in people's minds as a constant phrases, describing more the author's feeling's and state of mind, rather than the geographical properties of the place.
So, in respect of making people comprehend and remember the zone's names easier, I have decided that it would be much better to work with names that are quite common and understandable.
That way, in my opinion, they feel themselves in much more familiar environment.
And the fact that there are people who could find any resemblance between Imperial Hero and the biggest franchise in the world of gaming... can only flatter me and all my colleagues, involved in this most ambitious project.
