Story related, cannot be missed.
This achievement is for finishing the Tears of the Mountain portion of the main questline. After returning to Alya to turn in Fire on the Mountain, she will task you with this quest. Simply follow the waypoint to the Drenchfort. Here you will complete this dungeon (and fight an easy yet slightly fun end boss) to restore the water flowing down to the Maker's Forge.
Once this dungeon is complete, head to the Maker's Forge (just off the Tri-Stone location) and after a forced cutscene the achievement will be yours.
