Place it at the end of a raid wipe or betrayal montage, just after the moment a teammate walks away, and let it close the scene on its own. Open the sequence with Enemy Spotted to build tension, then follow this clip with Bomb Has Been Planted when the group falls apart completely.
About this sound
This is a short spoken line from C'Thun, lasting just under four seconds, delivered in a deep, distorted villain voice that makes the words feel like a warning from an ancient god. It feels ominous, cold and unsettling, turning a simple betrayal into something threatening. The line comes from World of Warcraft, where he is a boss who taunts players before a fight.
