No, actually it's not.

Bohavia was a fantasy country that I created as the setting for an online version of Dungeons and Dragons that began in the late 1990's and fizzled out after a few years. The above link will take you to the website for the campaign where there is plenty of information on it.

The setting for the country was based upon the Czech Republic which was where I was living at the time of the campaign. The name Bohavia comes from a combination of the two major areas of the Czech Republic - BOH-emia and Mor-AVIA.
