Located in the northwest corner of the map, Onrac serves as the entrance to the Sunken Shrine. Also available are half of the level 7 magic spells for both White and Black Wizards. Onrac is a bit of an oddity in that it doesn’t have a weapon or armor shop. It does, however, sell Hi-Potions, Ethers, and Remedies (in some versions of the game), making this town a one-stop-shop for end-game item purchases.
Note that you must first have obtained the Oxyale before you can enter the Sunken Shrine. Please see Chapter 9 :: Preparations if you need help finding the Oxyale.
