Armlock is a town in Energy Nede. It is located in the same area as the Fun City and northeast of the Minae Cave. It is a town dedicated to weapon creating, although the use of these is completely forbidden by the Nedian law.
The party reaches Armlock as a request of Nall, after their failure on the assault to Phynal. There, they enter through the "Sealed Door", a door leading to a building with a transporter, which teleports them to the remote Symbological Weapons Laboratory.
On their return from the facility, the party contacts Dr. Mirage, a weapon researcher resident in the town. Checking the weapon blueprints found in the Symbological Weapons Laboratory, Mirage warns that she needs the LEA Metal, a mineral found in the bodies of the Barchians from Minae Cave. Claude and Rena obtain it, and thus Mirage is able to create the Antimatter weapons.
Later, during the Wise Men's attack on Fun City, Metatron follows Mirage to Armlock. There, he breaks in her house and attacks her, but is confronted by Claude and the party, being defeated by them.
