Gobwins are a non-capital sideErf-b1-p079a and were Natural Allies to Gobwin Knob until the Volcano was uncroaked. They are about half the height of Men, have green skin, and fangs. The Erfwiki mascot (look in the upper-left of the window) is a gobwin spearman.
There may still be Decrypted Gobwins in Gobwin Knob, but they no longer part of the Gobwin side, cannot pop new Gobwins, and are not considered to be Natural Allies. Instead, they are simply Gobwin Knob units.  book image name not found Please Add to Template Erf-bFirst_Intermission-p045]

Prior to the reign of Stanley the Tool, Gobwins broke alliance with Gobwin Knob (which is not typical behavior for Natural Allies) captured the City and croaked King Saline IV.Erf-b1-p079 Stanley, who was a Heir Designate and Chief Warlord to Saline, then recaptured the city, and has been the Overlord ever since. Ansom believed that Stanley orchestrated this rebellion to come to powerErf-b1-p034; however, he lacked evidence for the accusation.
The Gobwin Insurrection, occuring after Wanda betrayed Faq and swore allegience to Stanley, was possibly orchestrated by Wanda alone. Where Stanley would have been controlled by Duty and disallowed from plotting against King Saline IV, Wanda had weak Loyalty and may simply have suggested Stanley take certain important Casters on a mission she had created. The Gobwins, manipulated by Wanda into believing they could hold the city by Suggestion Spells and/or more mundane methods, attacked the city and killed Saline. Stanley then returns to recapture the city with complete deniability, and no direct knowledge of Wanda's participation in the affair; thus, Loyalty, Duty, and Obedience are satisfied while Stanley takes command of Gobwin Knob.
Also, Wanda is more likely than Stanley to have the strategic thinking to pull off a maneuver like this. Wanda may have desired a leader who was more easily swayed when she still desired to attune to an Arkentool.
Gobwin Knob lost its contingent of Gobwins in the Volcano Uncroaking and is currently unable to find even a single Gobwin to recruit, despite an extensive search of some areas in which they normally pop. Why no Gobwins have yet been found is still unknown, but Lord Hamster suspects that Charlescomm may have a hand in this... (Note: A Gobwin can be seen in the foreground of panel two of Erf-b1-p146, after the Volcano uncroaking. What this means is unclear.)
With this new information another plausible senario for the gobwin revolt is that Charlescomm may have been behind it in order to force a change in leadership and drum up some new business.
