To get y'er character out ASAP without working on the map some more, head to the User Panel on the top right corner of the FH site. Log into the User Panel, find y'er character, and click "Send Home." This shall send him back to wherever ye set his home to or the default home, Lonely Cave.
Hope this helps deary! Best of luck with y'er map!
