This addon will mute the Bodyguard champion Lady S'theno. You must unzip this directly into your WoW directory (where you have the WTF, Data, Interface and etc folders).
You do NOT drop this addon into Interface!
It contains 3 blank .ogg sound files that prevent Lady S'theno spamming you verbally when in vehicles and on mounts when she vanishes and then re-appears. TOTALLY ANNOYING...
