- "Drop your weapon...or your son gets it."
- -Slyvo Spleethe
Slyvo Spleethe was the quartermaster of the Stormchaser. Ambitious, mutinous, and power-hungry, Spleethe wanted the Stormchaser for himself, and did a deal with the Leagues of Undertown. According to the deal, Spleethe would mutiny against Cloud Wolf, seize the Stormchaser and her cargo of stormphrax, and deliver it to the Leagues to prevent it from reaching the Treasury of Sanctaphrax. Spleethe sneaked Twig aboard for use as a bargaining chip. However, Spleethe failed, and he and his accomplice, Mugbutt, were killed.
