===The Undead Scourge===
An army of undead made by the Burning Legion to act as a replacement for the orcs.  The demon Kil'jaeden, second in command of the Burning Legion under Sargeras, made this army when he took an Orc named Ner'zhul and used unholy tortures to force him into forming this undead force.  After Ner'zhul agreed to serve Kil'jaeden again, his disembodied soul was put into a suit of armor frozen in a block of ice known as the Lich King.  During this time he experimented with dark magic and plagues, his main creation being a magical plague that turned creatures (mainly humans) into undead minions that were telepathically controlled by the Lich King.  After warring with some spider-people called Nerubians, he turned many of them into his undead minions and adopted their architectural style for the Scourge.  From then on he sent forces to Lorderaen.  There the plague was distributed by Kel'Thuzad, a mage from the human kingdoms who was fascinated with necromancy, went mad with power and made a deal with the Lich King that led to him becoming a lich.  They took over Northrend and Lordaeron. 

They were also kept on a short leash serving the Burning Legion by a subfaction of demons called the Dreadlords, since Ner'zhul was helping the Legion under duress and knew they considered him expendable.  He made an escape plan, using Arthas, a former human prince and paladin turned into an undead [[Blackguard|Death Knight]], as a pawn/host.  After helping Kel'thuzad and Ner'zhul uphold their end of the deal serving the Burning Legion, Ner'zhul got the Scourge to indirectly undermine the Legion.  With the dreadlords focused on helping their fellow demons and not paying attention to the undead, the Scourge went AWOL and started doing their own evil things.

After the Burning Legion's second defeat, Kil'jaeden was mad at the Lich King for going rogue so he looked for someone to kill him.  He eventually found and gave the task to Illidan Stormrage, a roguish Night Elf and light BDSM enthusiast, now turned to a renegade half-Night Elf, half-demon light BDSM enthusiast. (Though Illidan had no stakes in this game, this task was of the "offer you can't refuse" variety, the deal sweetened by Kil'jaeden offering to feed his magic crack addiction) Illidan gathered up his followers and used an artifact to melt the Lich King from two continents away, but Illidan was stopped halfway when his brother Malfurion <s>beat him up</s> nicely asked him to stop. Illidan was now forced to go to Northrend and finish the job in person, but he got his ass handed to him by <s>Spiderman</s> the undead leader of the spider-people and Arthas, now the Lich King's champion and the protagonist of the Undead campaign.

During all this, the Lich King's ice had cracked open and he wasn't feeling too well. Because he wasn't in top shape, about half of the Scourge woke up and threw off the Lich King's control, becoming a new faction called the Forsaken. The Forsaken took control of Lordaeron and would go on to do lots of evil of their own, but would maintain the image of being the edgy, morally-ambiguous faction. The Lich King got better by getting himself a new body by possessing/fusing with Arthas.  Arthas then preceded to beatdown Ner'zhul's spirit so he was calling the shots instead.  Though he would have to consolidate, this whole fiasco was more or less over, and the Lich King decided he needed some rest and took a nap for several years.  Though they were mostly quiet until the Wrath of the Lich King expansion, the Scourge continued actions to keep their hold on their half of Lordaeron, occasionally made some noise to remind the player base that they were still a thing, and also expanded to include such things as undead dragons and elf vampires.  

By the time the  Burning Legion showed up in... ''Legion'', the Lich King was now a former paladin named Bolvar, and he made an alliance with the Death Knights of the Ebon Blade (now led by the player characters) and has started to bolster his forces (angering the Red Dragonflight and stepping on the toes of the Paladin order in the process) to fight the demons.  However, there were rumblings that Lich King Bolvar wouldn't keep the Scourge passive for much longer, but these have been waylaid as Sylvanas made a deal with a major death entity and her Grim Reaper sugar daddy gave her powers that allowed her to plot armor her way to victory over the Lich King.  He was last seen chained up on Icecrown while Sylvanas shattered the helm, destroying the Lich King as an entity but still keeping undead Bolvar as the Scourge boss-man.
