"It seems the Blacktooth Grin can't figure out there's more than the Knights of Dusk to play with. They've pinned the little stunt Jack and I pulled a few weeks ago on the Knights and retaliated in kind." Dash turned to the draenei, Kaylin, sitting in the chair facing away from the fireplace. "I think it's time we sent them a message. Gather the Vigil and send word to the Gathering, the Guardians of the Light, the Council of Judgement, Divine Vengeance, the Knights of Dusk, the Dreamers Masque, the Coven, the Hallowed Remnants and the Warbringers. We strike in this coming week and I want it well known that the creation of this war is the doing of the Vigil."
This is exactly what it says on the tin. The Vigil is, in coordination with many, many other guilds, gathering forces for an attack the week of December 3rd. If any (preferably high-level) role-players or PVPers are interested in this event, contact Dashadeash ("Dash" in-character) for specifics, although it's likely SOMEBODY in CallToArms already has assist for an event invite and information on how to get involved.
If any Horde members want to help make this an even match, my Battletag is available upon request. A war isn't a war without two sides.
