After a long battle to clear the plague lands of the scourge threat Tirion and his loyal followers come upon a new sight not seen before by most of the new recuits. The forsaken lead by their Queen are using the Val'kyr to ressurect the fallen soilders of the alliance, horde and crusade alike.
Furious at this abomination he demands a stop to this act at once and tells the forsaken to return home and leave the fallen warriors be. After a moment of silence sylvanas windrunner begins to laugh at the request and tells Tirion that relics like him do not belong in the plague lands anymore and for him to leave her domain.
Tirion marches the new recuits back to hearthglen to conviene his council, darion mograine and the knights of the ebon blade answer the call of their old ally and ask him to see reason. Darion tells Tirion that the forsaken are not like the Lich king and offer free will and not slavery.
Unbeknownst to all the forsaken queen had taken insult to the comments made by Tirion early that day and now lead a force upon hearthglen. After the fighting begins Tirion calls for Darion to aid him, but the deathknight and his force leave the fight and stand beside sylvanas windrunner. He says that his knights are now her's to command. She turns and says with that fool Bragor Bloodfist gone Darion shall now stand as her Second in command.
Tirion is able to escape with a small force and make for the lights hope chapel, with the loss of Hearthglen and the actions of the forsaken Tirion proclaims the Argent Crusade no more, he renames the new force the Argent Retaliation who's sole purpose is to rid azeroth of the forsaken and its ilk. Upon hearing this the horde members leave the chapel in protest.
Tirion understands that to stand alone against the odds would be too great a task for any group and such offers his services and rescources to the alliance.
The stage is set with the knights of the ebon blade and darion siding with the forsaken, while Tirion Fordring and the Argent Retaliation rejoining the alliance.
