Sen'jin lived a relatively peaceful on the remote Darkspear Islands life until new troubles began. Humans from Kul Tiras came to the island and made a settlement, pushing the trolls further into the island. Meanwhile, the once-docile murlocs had become fevered, prodded by the dark Sea Witch that lived in the ocean, who they offered sacrifices to.
That soon came true. As Sen'jin's visions reported, and his fleet were forced to moor on his island after the Maelstrom nearly destroyed his ships. Sen'jin approached the orcs, warning them of the humans nearby. Thrall promised to force the humans from his island. After defeating the humans's leader, an archmage, and forcing them into a retreat, they were suddenly attacked by murlocs who captured Sen'jin's trolls, the witch-doctor himself, Thrall, some of the orcs and the remaining humans.
Thrall managed to escape the prison and rescued many orcs and trolls, but a murloc high sorcerer took Sen'jin into the deepest part of the underground lair, where he brutally attacked him and sacrificed him to the Sea Witch just as Thrall arrived. Thrall battled through the murlocs and finally destroyed the murloc high sorcerer, but Sen'jin's wounds were deep, and he was dying.
In his last breath, Sen'jin implored Thrall to take his people from the island and save them from destruction. Following his death, Sen'jin seems to have taken a place among the loa.
