Horseshoes of Flight

Flight is not unheard of in Martapa.  After all, people use to fly upon dragons and pegasi.  Most flight in the time of the High King's Sword, though, has to be magical.  About two hundred years prior there was a Knight who took the winged horse as his standard and thus really wanted his mount to fly.  He consulted some mages and after some research and lots of gold passing hands the mages created him a set of magical horseshoes which allowed his mount to fly.  He would charge onto battle fields from above, frighting foes and winning the day.  It was said, that one day he was in a battle and his horse was slain as he tried to fly in and he was killed, as well.  The fate of the horseshoes are unknown, but many copies have popped up around the realm through the years.  The horse must be fitted with four shoes, all enchanted together, for the flying to work.  And when the horse is told to fly the first few times the riders must make a difficult riding check since the horse will not be happy about being off the ground.
