Gobwins are a non-capital sideErf-b1-p079a and were Natural Allies to Gobwin Knob until the Volcano was uncroaked. Charlie subsequently convinced all other gobwins in the area to join Charlescomm. 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 are still Decrypted Gobwins in Gobwin Knob, but these are no longer part of the Gobwin tribe, cannot pop new Gobwins, and are not considered to be Natural Allies. Instead, they are simply Gobwin Knob units.LIAB Prologue 24
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 an 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 allegiance 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, Charlie, 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, especially when he learns that Charlie has a special affinity for natural allies. This is later confirmed when Charlie reveals himself to have hired them against Gobwin Knob.
With this new information another plausible scenario 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. This might have also been part of a long term plan to weaken Gobwin Knob under Stanley's leadership and cause conflict with Jetstone. This would have allowed Charlie to scoop the Arkenhammer and the Arkenpliers.
