Unto Elder Crone Magatha of the Grimtotem,
Acting Warchief of the Horde, Garrosh Hellscream,
Sends his most sincere wishes for a slow and painful death.
It has come to my attention that you have deprived me of a rightful kill. Cairne Bloodhoof was a hero to the Horde and an honorable member of a usually honorable race. It is with disgust and anger that I discover you have caused me to bring about his death through accidental treachery.
Such tactics may work well for your renegade, honorless tribe and Alliance scum, but I despise them. It was my wish to fight Cairne fairly, and win or lose by my own skill or lack of it. Now I shall never know, and the cry of traitor will dog my steps until such time as I can sport your head on a pike and point to you as the real traitor.
So ... no. I will not be sending any truehearted orcs to fight alongside your treacherous, belly-crawling tribe. Your victory or your defeat is in the hands of your Earth Mother now. Either way, I look forward to hearing of your demise.
You are on your own, Magatha, as friendless and disliked as you have ever been. Perhaps more. Enjoy your loneliness.
