In an alternative timeline, Thrall died as an infant. Robbed of his ultimate weapon and most efficient method of taking over the Alliance, Blackmoore did the unexpected - instead of going further down his drunken path, he sobered up, conscripted mercenaries, and trained his would-be army himself. His hands-on approach won him popular support, and Blackmoore himself led the charge into Blackrock Spire. He even managed to kill Orgrim Doomhammer in single combat, dealing the Horde a devastating blow. Rather than having the defeated orcs put into internment camps, Blackmoore gave them a choice: join his private army or die.
Blackmoore returned triumphantly to Lordaeron and, in a swathe of destruction, he and his orcs killed several of the most stalwart defenders of humanity and dethroned the House of Menethil. He then became the self-proclaimed King of Lordaeron, assisted by his duplicitous advisor, Kel'Thuzad. He even had Doomhammer's plate reforged into a suit of armor for himself. He was not a well-loved ruler, and Varian Wrynn even planned to restore Arthas and his wife Jaina to the throne of Lordaeron, both of whom had fled to the safety of Stormwind in the aftermath of Blackmoore's coup. His rule ended after about twenty years (probably less), when he mysteriously disappeared, having been taken by the infinite dragonflight in order to kill Thrall in the original timeline. After chasing Thrall across the timeways, they eventually clashed in the Dragonblight, where Blackmoore was killed once again by Thrall.
