Now keep in mind that it needs to go back to its lair to sleep. 11.25/2=5.625 miles maximum distance from its lair. This, of course, assumes that it always stays awake for the maximum length, and that it moves at maximum speed the whole time.
It would be 90 miles a day (330*60*24/5280)=90....not that it makes a major difference when magic based forms of travel are available
