The Crystal Line

After receiving the mission, talk to Cid in the Metalworks. He will give you a crystal and tell you to trade it to the Telepoint at the Crag of Dem to see what happens. Leave from Bastok Mines or Markets so you'll zone to South Gustaberg. Zone to North Gustaberg from (E-6) of South Gustaberg, in the northwest corner. Then head north and zone to Konschtat Highlands. The Crag of Dem is located at (I-7)/(J-7) of the zone. After zoning to the Highlands from Gustaberg, follow the path and keep to the paths to the right. They lead out to the Crag of Dem. Trade the crystal to the Telepoint at the Crag. You'll recieve a Faded Crystal. Take the crystal back to Cid, and then go and talk to Ayame in the cannon room behind the President's office in the Metalworks to complete the mission.
