From ErfWiki

Proposed Canon

Gobwins are a non-capital side^Erf-b1-p079a and are Natural Allies to Gobwin Knob. They are smaller 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.

Speculation

The side consists primarily of gobwins. It is not clear whether Hobgobwins (who are a different unit) are a separate side or a part of Gobwins side.

Diplomacy

During the Battle for Gobwin Knob Gobwins were allied with Gobwin Knob and constituted a significant part of its forces.^Erf-b1-p077a

On one occasion Gobwins broke alliance with Gobwin Knob (which Sizemore considers very odd), captured the city and croaked King Saline IV.^Erf-b1-p079 Stanley who was a Heir Designate to King Saline IV recaptured the city and became Ruler, an Overlord. Ansom believed that Stanley orchestrated this rebellion to come to power.^Erf-b1-p034
