Back in the Darkspear islands, Gadrin was the chief witch doctor of the tribe and the mentor of Vol'jin and Zalazane who also called him Gad. After the two returned from their adventure in First Home, Gadrin told them about the death of Sen'jin and orcs, but Vol'jin already knew this thanks to his visions while in First Home.
As they had foreseen the lord of the orcish clans, Thrall arrived at the Darkspear islands, and rescued the tribe from the powerful Sea Witch. After settling in Kalimdor he invited the trolls into the Horde, where Gadrin became one of Vol'jin's most trusted advisors at their new home on the Echo Isles. Along with the young witch doctor Zalazane, Gadrin led the mystical training of many Darkspear priests and mages. However, Zalazane went mad from the mystical forces he had unleashed. The crazed witch doctor placed a curse upon the Echo Isles and drove Gadrin and his brethren away. Until Zalazane's Fall, Gadrin sought to end his rampage and put the souls of his cursed brethren to rest.
Gadrin's deceased brother, Minshina, was calling him during his dreams, so he decided to send adventurers to retrieve Minshina's skull from the Echo Isles.
Before the Echo Isles were liberated shortly before the Shattering, he instructed the adventurers to gather tiki masks in order to put deceased trolls from the isles to rest. He also worked with them in order to summon Elortha no Shadra.

Following the Argus Campaign, as a troll representative, Gadrin was present in Spirit Rise in Thunder Bluff standing next to Baine Bloodhoof shortly before Magni Bronzebeard arrived to speak about the healing of Azeroth. Sylvanas wasn't looking forward to the conversation with Gadrin.
Battle for Azeroth
This section concerns content related to Battle for Azeroth.
Since Vol'jin's death, Gadrin says that he often has felt Vol'jin's spirit whispering to him. His strength was the lifeblood of the Darkspear, and some would even say he was the spirit of the true Horde.
Gadrin later carried Vol'jin's ashes to Atal'Dazar, the burial site of Zandalari kings. Along the Golden Road up Mount Mugamba Gadrin told of Vol'jin's past deeds to honor him, even as the Sandfury, Gurubashi, and Amani tribes fought to keep the ashes of a "Horde-loving traitor" out of Atal'Dazar.
It was eventually discovered that Vol'jin's spirit was not in his urn, which deeply concerned Bwonsamdi. He tasked Gadrin, Talanji and Rokhan with performing a seance to find the lost Warchief. With the presence of his old teacher and friend, Vol'jin appeared, not to reveal what happened to him, but to say that the Shadowlands were in turmoil: G'hunn's influence was spreading without the Grand Seal, and trolls of the past and present alike cried out for justice against the Blood God. The time to end G'hunn was nigh and Vol'jin requested they use his glaive to stab G'hunn's corpse to draw his blood and show all of Zandalar that the old god is dead. Talanji then accompanied a team of Horde adventurers into the Underrot and Uldir to defeat G'huun and Gadrin was present when Talanji presented their victory over G'hunn to the Zandalari Empire.
Tides of Vengeance
Gadrin was present at Rastakhan's funeral after the Battle of Dazar'alor. Later, at Baine Bloodhoof's request, he performed another seance with Talanji and Spiritwalker Ebonhorn to call on the spirit of Vol'jin once again. When Baine asked Vol'jin who it was that had told him on his deathbed to make Sylvanas the new warchief, spirits of the dead attacked to silence the question. Gadrin returned to Orgrimmar to call on Vol'jin's spirit at the site of his funeral pyre, with Bwemba's help, to search for answers.

- He knows the Witherbark trolls well.
- Master Gadrin's greeting line "Eekum Bokum!" is a reference to Mumbo Jumbo, a witch doctor from the Banjo-Kazooie video game series.
Though the Darkspear have no official leader after Vol'jin's death, Gadrin appears to have stepped up to the plate unofficially by Battle for Azeroth as shown in the Echo Isles questline.
