The emerald green Hullback wood was originally found only on the Rest islands. In 1834, seedlings of this resilient timber were procured by agents of the Tyrian League. Hullback saplings are now being cultivated in other tropical regions. This exceptionally sturdy wood is primarily utilized for constructing ship hulls, enhancing a vessel's hit points by 30% and increasing its speed by 2 miles per hour.
The inaugural vessels constructed with hullback were the Gyalech Speeders.
