Instructions
Travel to the Machine City Goug after killing the Lucavi Demon named Adramelk to see a cut-scene with Mustadio's dad showing off a large metal relic he has excavated.
Leave Goug once the scene is finished and go to the Coal City Goland and listen to all the rumors at the bar until you hear a rumor about monstrous creatures in the mines.
Go from Goland to the city named Lesalia and again listen to the rumors at the bar. When you try to leave the city a Temple Knight named Beowulf will stop you and ask to come along. Accept his offer and return to Coal City Goland.
Battle the monsters in the mines of Goland until you reach the bottom and see a holy dragon being attacked by several creatures. Kill all of the monsters here to discover that the holy dragon is actually a woman named Reis whom Beowulf has been searching for. After the battle Reis will join the group as a guest, but is not yet a permanent member.
Walk back to Machine City Goug and watch another cut-scene involving the excavated relic. Leave Goug and go to the Trade City Zarghidas. While there, a girl will ask the party to buy some flowers. Choose the dialog option to buy the flowers from her, then go back to Goug yet again to see another cut-scene.
Head away from Goug and to the castle called Zeltennia. Listen to the rumors in the bar until you hear a rumor about a hidden temple on a cursed island. This will open up a new area on the map. Go to the new area labeled "Nelveska Temple."
Fight the robot at Nelveska Temple and then go back to Zeltennia Castle once the battle is over, where the party will use a Zodiac Stone to turn Reis into a human and she will then permanently join the group as a playable character.
