This script works in conjunction with Psylin's CMud maps to automatically travel around all of the locations for the "Secrets of Stonehenge" quest, just import this XML, ensure your character is FLYING and preferably already in Medieval somewhere, and type MERLIN.
Now you can go away and make a cup of tea.... when you return you should be just finishing up.
Updated with instructions for terminating the script, and tidied up some map things near Tintagel since the down exit room was a bit problematic in Psylins map, and finally adjusted some of the waits.
