In 102 GUE, the citizens of Mareilon were dissatisfied with the new regime of Quendor rulership. These quibblings gave birth to Mareilon’s abortive, near-comical Frobbish Rebellion. Little is known about this event, and only two minute details have emerged: the Eagle’s Claw Tavern was the headquarters of the revolution for a brief two weeks, and that afterward Zylon the Aged became known as the "Preserver of Peace in the Time of the Frobbish Rebellion".
