Dark Citadel, Kingdom of Garan, North of Eostia

Vult, the leader of sellsword company called: the Black Dogs, who were hired by their employer Celestine Lucullus, the High Elf Goddess Reborn and leader of the Seven Shield Alliance who given a task to storm the Dark Citadel, the stronghld of Olga Discordia, the Queen of the Dark Elves and leader of the Legion of Darkness, to capture her alive and ending the long conflict of Hundred Years' War.

He was known the Hero of Eostia, the People's Champion, and King of the Sellswords who brought victory over Olga's monster legions which he loved by the people of Eostia. Behind those wonderful tales is nothing but a lie for he has scheming plans of his own by turning the land into a Sex Empire: a Nation of Servitude and Pleasure, where ALL women including the Shield Princesses to become sex slaves to serve and please the wicked men. He managed to convinced the monsters of the Legion of Darkness to side switch side so they can have the pleasure of Olga which they accept.

As Vult's Black Dog growing army of Orcs, Red Imps, Ogres numbering 100,000 are marching towards the Dark Citadel where Queen Olga Discordia along her attendant adviser Chloe, her general Algrim the Strong, Engineer, Spy, Soldier, Scout, Demoman, Medic, Heavy, Sniper, Pyro and a hooded stranger wearing snowy white cloak worn over the armor including Army of Dark Elves numbering 35,500 standing outside of the citadel which made Vult arrogantly smile that he hit the jackpot of victory.

Until. . .

Nine glyphs appears out of nowhere which made Vult halt his army as the glyphs keeps hovering and then came out nine purple metallic siege machines (aka Carrier Tanks) with designs they never seen came out from the glyphs. Nine siege machines stops moving which made Vult's army back away a little but some remain strong.

(Play: Team Fortress 2 – Mann vs. Machine – Robots!)

In the front of the strange machines open a metallic plank landing on the ground and it came out of constructs, metallic constructs (aka Engineer Robots, Heavy Robots, Scout Robots, Demoman Robots, Medic Robots, Spy Robots, Sniper Robots, Soldier Robots, and Pyro Robots) carrying strange weapons they never seen. More and more metallic constructs came out from the nine siege machines are numbering 358,000 that are now joining Olga's side.

"Goddess help us." Hicks, Vult's second-in-command of the Black Dogs, said as his eyes widen in shock that seeing of Olga's new army.

"I don't think she can." Kin, Vult's adviser and mage, said as eyes also widen in shock that seeing an army of metallic constructs.

Vult gritted his teeth in anger seeing that his army are outnumbered by Olga's army and he suspects of the white hooded stranger's doing, he sees the stranger making a mock salute which made Vult more MAD. As two armies facing each other and the white hooded stranger said to Olga calmy.

"Would you like to say a few words, milady."

Olga raising her scepter which the top of the purple gem glows and pointing at Vult's Black Dogs and the traitorous monsters then shouted outloud.

"Slaughter them ALL!"

The RED mercenaries, Algrim and Chloe army of Dark Elves and the Machines made a roar of war cry as they charge towards the Black Dogs.

"CHARGE!" Vult shouted to to his army as he unsheathe his broadsword from the back and pointed to Olga's army with war cry well.

(Ending: Team Fortress 2 – Mann vs. Machine – Robots!)

Narrator with French accent: "Seven hours later. . ."

After a viscious battle for seven hours, Vult and his army are defeated by Olga's army. All members of the Black Dogs and their monster allies were all killed in the battlefield. Only Vult, Hicks and Kin survives and were kept alive inside the citadel's dungeons as Olga and her ally the white hooded stranger torture them without remorse and gathering information all their plans and their collaborating allies within the Alliance.

Three months later. . .

Dark Citadel's dungeons

Vult the self-style King of Sex Empire was a downtrodden loser as his body covered of bruises and scars from the dreadful torture. His two loyal subordinates died from snu-snu from the sucubuss. Then he hear the sound of footsteps approaching Vult's dungeon and standing there was the white hooded stranger that help Olga which irritates Vult.

"What do you want?" Vult sneers the stranger.

"Hmm, what I want? Oh, yes, to tell you that your allies are GONE. Your ambition and reputation are also GONE. Your so-called Sex Empire is GONE. Face it, Vult, you've lost." The white hooded stranger taunting the fallen sellsword which made Vult's blood boiled in anger as he stands up running towards the bars as he tried to reach the stranger but it didn't reach him an inch.

"By the way, Olga and Celestine are already married and their having honeymoon on the beach which you'll never reach them. Claudia's husband Klaus was cured by Medic and they made non-stop session in their bedroom which I find very steamy romantic. Your ex-compatriot Maia is dating with the priestess Kaguya. Scout dating both Chloe and Alicia, man, that guy is lucky. Heavy and Luu-Luu love each other no matter what their races. Soldier training new generation of youngsters to become proper soldiers of Eostia. Spy married Scout's mother which he didn't object. Sniper married a fine warrior woman at the Adventurer's Guild. Demoman bought an abadoned brewery to start his own Scrumpy business on Eostia. And lastly Engineer finally found a woman that he can love. That leaves nothing, Vult." He chuckles as Vult tried to reach him and shouted madly.

"How dare you, how dare you, HOW DARE YOU MOTHERFUCKER!"

The white hooded stranger holds Vult's arms. "My face will be the last thing your pathetic eyes ever see." He twisted as Vult screams in agony then dropped on the floor crawling away from the stranger walks away passing Pyro.

"He's all yours, Pyro."

Pyro mumbling back saying 'thanks' as his pointed his flamethrower towards the fallen sellsword leader as he too late to scream and the flames consumes him that turned into ash.
