Take the boat to the north east of Marion, and you will find a alcove of rocks. If you sail to the end of this alcove, you will be able to get off the boat and on the rocks. Travel 1 space east and you will enter a cave. In the cave is a pot. Look in the pot and Merlin the master magician will appear and give one of your characters the Resurrection Spell. Don't forget to look in the flames around the pot. There's some cool stuff in there.
