Qual-Kehk is the Barbarian Mercenary Captain from Harrogath. He gives you the Rescue on Mount Arreat quest and lets you hire the Barbarian Warriors you rescued, if the quest is completed. Additionally, he gives you the runes Ral, Ort, and Tal, which, when put into a three socketed shield in that order, makes the runeword "Ancient's Pledge." What became of him when a huge region around Mount Arreat was devastated when the Worldstone was destroyed is unknown. He either evacuated to safety, or perished within.
