Zuni is a Darkspeartroll recruit who accompanies new troll players on several quests throughout levels 1-5. He is first seen when you have completed your training and are tasked with the quest  A Troll's Truest Companion and talks to you as you cross the bridge to help obtain raptors. During two later quests  No More Mercy and  Territorial Fetish he assists you in killing the naga that are trying to take over the Echo Isles, led by Zar'jira. Near the end of the fight with Zar'jira during the quest  An Ancient Enemy he runs behind her to stamp out the braziers that give fuel to her powers. Zar'jira notices that he is doing this and casts a Frostwave, killing him instantly. After being killed, Vol'jin asks Vanira to heal Zuni, but when she attempts to you found out that Zar'jira ripped his soul from his body, forever killing him.
Even though he is only located in the starting zone and is killed, he is fully voice acted giving him far more depth than is usual for such a minor character.
Because he is fully voice acted, Zuni enjoys a mild degree of fame among Horde players and is featured in several cross-server recurring jokes such as reacting with overwrought grief at the mention of him.
