After you get Roan for the second time, leave Cyrum Kingdom and go to Raul Hills and it will be a special stage. Go through there and get to the ruins in Raul Hills 1. When you get to the ruins you will encounter Devils. They are extremely hard to fight. Ice will work best but make sure you have items that refill SP and MP because there are no recovery spots, and if you go back the enemies will reappear. Inside the ruins are items including armor, an item that doubles SP earned, one that doubles EXP earned, and one that gives you 1000 Magic Coins. The Fairy egg can be found on top the highest pillar.
