Kezzig Klackwhistle is an Azerite miner who was located in Silithus after the Argus Campaign. Originally from Winterspring, Kezzig used to work for Lunnix Sprocketslip. The two entered a relationship but was forced to leave when she caught him hanging out with Gogo. He was then a part of the extraction team that attacked the camp of the Explorers' League expedition guarded by the Sentinels. Kezzig personally caught Sapphronetta Flivvers and brought her to Druz and Grizzek Fizzwrench to Tanaris. Kezzig, Druz and the other guards later caught the fleeing Saffy and Grizzek. He took Saffy's notes, set a bomb and placed it between the bound gnome and goblin.
Given he used to work in Everlook, he could have been a member of the Steamwheedle Cartel.
