Zekhan, the beloved troll from World of Warcraft: Battle for Azeroth’s cinematics, will finally find a place in-game in its next patch. In the upcoming Tides of Vengeance patch, players have datamined voice lines for Zekhan. On the public test realm, Zekhan is currently using a generic model, but that could change before the patch is officially released. If everything makes it out of the public test realm without getting cut, it seems like players will get the chance to go on a quest or two with him as well.
