Shadowspinner was one of the Shadowmasters. During the Siege of Dejagore he led the Shadowmaster's army and defeated Croaker's forces, although suffering some substantial injuries. He besieged Dejagore with his remaining forces. Once Lady rebuilt the army of Taglios and tried to reclaim Dejagore he flooded the city so that he did not have to fight on two fronts. He was eventually killed in his own tent by Lady and her Stranglers.
In the days of old, before the reign of the Shadowmasters over the Shadowlands, Shadowspinner served as Longshadow's apprentice. This apprenticeship ended when Longshadow betrayed him during their war against the Shadowmasters Moonshadow and Stormshadow.
