Historical Fantasy

What is historical fantasy?  The Tales of Tiberius are set in a fictional region which has been colonized by Europe much as were the American Colonies.  While some things are fantastic and magical, most of the world is a realm of historical fiction.  So while Tiberius the Magus may be able to teleport around the countryside, for the average citizien of the Stewardship, boats and horses don’t go any faster than they did back in Colonial America.  I do a lot of historical research trying to get the details right.  Hopefully we can have some fun and learn a few things kicking around some questions of history here.
