How do I get out of Ola Ola (on Maplestory)?

I was playing the mmorpg "Maplestory" with a friend when all of a sudden he was taken to this weird place called Ola Ola. He talked to this priest person in front of the Cathedral in Amoria and then he was taken there! I thought I could help him by using my Mystic Door ability to warp us back to Amoria buuuut it didn't work out! Pretty much all we can do is walk and attack. We've tried EVERYTHING...or so we thought. Do you guys have any ideas??
