There is a secret dungeon in the game called the "Cave Of Trials". To unlock it, you must use the save point right before fighting Gabriel. Your save icon should turn blue. Then, return to the arena in Fun City, and talk to the old man in the stands in the north side of the arena. He says he can recover your memories; accept, and you'll return to Arlia on Expel. Leave Arlia and you'll have your Psynard; the Cave Of Trials is located at the lone dot on the desert island, southwest on the world map.
