Heart of the World Lung

The players must recover the "Copper-Pot Tuning Fork," an artifact that Engineer Fidddlestick created to calibrate the resonance of his machines. Legend says that it was buried with his apprentice, one of the "Vanguard of the Verdant Heart" survivors on Gravelight Isle, a small fragment of the Sky Reach Mountain Range, which was last known to be stuck in a high-turbulence zone.   Stages 1. Call to the Depths. The players are summoned to the Sub-Spires by Chief Engineer Pip Whiffle. The environment around the city is becoming "heavy" with the raw, unvented magical static that makes people's hair stand on end and causes static discharge when touching metal.

• Technical Crisis: Pip reveals that the Sentinel's Aetheric Diaphragm (a massive sheet of woven Oriculum silk) has lost its tension. Without the Tuning Fork to reset the "Prime Note," any unskilled attempt to alter it can cause a catastrophic energy back-surge.
• Time Limit: The city has 72 hours before the static levels will become dangerous and possibly spontaneously combust.

2. Navigating the Gravelight Void

To reach the Gravelight Isle, the players are provided with a modified Cloud Hopper Training Skiff. Since the island is caught in a "gravity shear eddy," standard flight is impossible.
• Skiff Modification: Players must help Pip install "Relonance Dampers," primitive lead-and-amber weights that keep the Liftwood hull from vibrating apart.
• Hazard: The pilot must succeed in a DC 20 Profession (pilot) check to navigate the "entry angle. Failure doesn't result in a crash, but it will cause you to bounce off the sheer, knocking everyone out for 8 hours.

3. Tomb of the First Mender The Gravelight Isle is a frozen, crystalline wasteland. At its center is the tomb of Soot-Hand Silvertide, Fiddlestick's lead apprentice.

• Environmental Hazard: the island is "un-phasing." Every 10 minutes, the terrain shifts, requiring Perception or Survival
