First of all, trolls have two empires, Gulabash and Lamani. Gulaba is mainly distributed in today's Lordaeron and further north, and Lamani is mainly distributed in today's Thorn Valley. The dark spear troll played by the player is part of the Lamani empire. In order to stay away from the war, they moved to an island further south of Thorn Valley and settled down. There used to be fishermen on that island, but these inferior creatures are everywhere, which is not enough to pose a threat to trolls. But then, a group of humans came and began to attack the troll. At the same time, the fisherman seems to have gained some strength, started to become smart and kill, and began to attack trolls. The dark spear couldn't resist, and at the same time, the old patriarch had a dream that green friends would come to help them, and Sal came. Thrall is a god sent by trolls and led them to defeat mankind. But the old patriarch was killed by a fisherman. The rest of the trolls migrated with Sal, and served the tribe because Sal was kind enough to save them until the present Senjin village.
