Eastbridge was a small village established during the cataclysmic Third Age and a point of combat during the time. It has since presumably been destroyed, and thus has not seen in RuneScape. It is, however, a point of play in the FunOrb game Armies of Gielinor.
Eastbridge was apparently a village settlement built on a small islet off the coast of an unknown region, although it was likely within one of the wooded areas that are now Misthalin, Asgarnia, and Kandarin. It was occupied at one point by barbarian and rogue TzHaar forces during an unlikely alliance, but was later conquered. Consisting of small huts and a central fortress, Eastbridge was a key strategic point in the region, but did not survive the God Wars.
