In an effort to break the ceasefire forced upon the Horde by the fool, Varian Wrynn, The Grim concocted a scheme to assassinate all the heads of each major Alliance nation. A rapidly assembled war group, with Horde allies, was sent to Ironforge to begin the slaughter.
Unfortunately, due to the arrival of the Iron Horde, the Alliance leadership had prepared and trained themselves to new heights. While the newly trained guards were defeatable, the Council of Three Hammers proved too much for The Grim and their allies to overcome. In light of this new information, The Grim cut their losses and withdrew from the city.
However, the Alliance were not going to go unbloodied. In succession, The Grim visited Darkshire, Lakeshire, Goldshire, and the very gates of Stormwind itself, to deliver a message that Peace Through Annihilation was only delayed, and that the meaningless ceasefire imposed by the pinkskins and their dogs was worth less than the scrap of parchment it was written on.
