Hullback is an emerald green wood. It was originally only found on Rest. In 1834, seedlings of this wood were stole by agents of the Tyrian League. Seedlings of this very strong wood are now being planted in other tropical areas. The wood is mostly used for ship hulls. It increases the hit points of a ship by 30% and increases speed by 2MPH.
The first vessels that were constructed with hullback were the Gyalech Speeders.
