Darkspear Islands The Darkspear Islands were the former home of the Darkspear tribe near the Maelstrom in the South Seas . Thrall and the orcs had shipwrecked on one " lone island " , within the Darkspear islands . The Alliance had set up a small outpost on the island , and Thrall was forced to destroy it in order to help out the Darkspear trolls who had been harassed by the forces . The island also had ogre s , wolves , golem s , gnoll s , and lizard s . Thrall found active volcanic vents which he thought may mean trouble in the near future . Soon after they were captured by murloc s and were taken underground . Under the island was an underground cavern system called the Underworld which served as a prison , mine , and temple for the Underworld Minions and their goddess the Sea Witch . Her minions included murlocs , ghosts , a tome wraith , sludges , skeletons , spiders , golems , and gnolls . Murloc s would kidnap races and take them into the cavern to be sacrificed to their goddess . Thrall fought his way out and Darkspear ' s leader , Sen ' Jin was killed . The island was destroyed by the Sea Witch and her murlocs , and began to sink . Thrall was forced to hold off the murloc forces and the sea witch until he could get everyone off the island . The Darkspear tribe had lost their homeland — which had sunk to the bottom of the sea — and they agreed to travel to Kalimdor with Thrall . History . During the Troll Wars , the Jungle trolls of the Darkspear tribe exiled themselves out of Stranglethorn Vale and decided to settle somewhere else in the world of Azeroth . Months after the death of Hakkar the Soulflayer , the Darkspear Jungle trolls managed to find a pair of islands . During the time of the Third War , in which the Horde left Lordaeron behind , the Orc Shaman Thrall led a stolen fleet that was scattered and heavily damaged by a fierce thunderstorm . While the ships that remained with Thrall happened upon the Darkspear Islands , Thrall and his fleet began to repair their vessels until they made contact with the Darkspear ' s leader Sen ' jin , the father of Vol ' jin . When the Horde discovered that the human s of Kul Tiras had built an outpost on one of the Darkspear Island , Thrall led his best troops and to rid of them off the Darkspear ' s settlement before the Alliance could rally the strength to threaten the Orcs and Jungle trolls . Before the humans could do that , they were ambushed by an unnamed tribe of murloc s that led a suprise attack . Now that both forces were caught off - guard , and Thrall , Sen ' jin , hundreds of Orcs , thousands of Jungle trolls , and many Alliance survivors found themselves captured . Taken to an underground cavern system , the murlocs presented their prisoners to their leader , Zar ' jira . Eventually , Thrall fought his way out , merging the Alliance and Horde prisoners to fight together , but during the fight , Sen ' jin was badly wounded by the murlocs and as the caves began to collapse , the father of Vol ' jin told Thrall that it was he who would lead his people off the islands , according to his vision . Thrall brought the trolls to forever join and be part of the Horde . Without hestiating , the Jungle trolls of the Darkspear proudly accepted Thrall ' s offer and would settle in a new home that would be safe for them to live and survive . Zar ' jira was very enraged after her temple had fallen and immediately caused one of the island ' s volcano to erupt . During the volcano ' s eruption , the sadistic Sea Witch began to attack the Thrall ' s camp while the Alliance and Horde ships ' were fully repaired and ready to leave . As the Murlocs tried to stop them from escaping , Thrall decided to stay behind and give his forces to evacuate safely while he held off the enemy and reduced all the Jungle trolls to be brought with them . The island was thought to be destroyed by the Zar ' jira when the Horde sailed away to Kalimdor , but it turns out that it hadn ' t . Thousands of Jungle trolls remained on the islands , including one of their leaders Master Gadrin , and would remain in contact with their Horde allies and driving off the Murlocs that continued to threaten them . After several months , Vol ' jin and Zalazane returned to the Darkspear Islands and all the remaining Jungle trolls prepared to make their final leave and rejoin the rest of the Darkspear trolls in Durotar .
