Jerinvar Barstere is the mayor of Watch Hill.
Jerinvar was in office as Watch Hill's mayor in 999 NE when Dain Bornhald occupied his town with a force of Whitecloaks. As troubles mounted in the Two Rivers, he and others in his village became concerned for the security of Emond's Field - most especially after seeing smoke rising to the south of their area. Eventually, a plea for aid was personally delivered by Faile Bashere and Jerinvar responded immediately by mustering all men and boys of fighting age to join their southern neighbors in battle. After a days march he and his men arrived to participate in the final hour of the Battle of Emond's Field and helped to defeat the shadowspawn attempting to penetrate the north defensive perimeter around the village.
At the conclusion of the battle he approached Perrin Aybara with the Watch Hill Village Council to assure Perrin that the people of Emond's Field can always count on Watch Hill to help in times of need. After deferring to Perrin and Faile - as if to sovereign lords - he leads his men back to Watch Hill.
