Erda/ the Queen in Black

(I don't think Erda has ever been called the Queen in Black in cannon. I just think it sounds cool so thats why I'm giving her this tital.)

The Emperor was not the only near imortal, increadably powerful human. There where other known as Perpetuals. The Emperor recruited many Perpetuals to his side. However soon they realized the Emperor was a brutal tyrant and either left or tried to kill him. Only 2 Perpetuals stayed loyal. 1 of these 2 where Erda.

She disagreed with his ways but believed he was only like this for humanitys sake. She was the Emperor's longest companion. She also gave the Emperor her egg cells to make the Primarch's. However she saw him altering they're genes to make them into wepons. She knew then that he was a monster and she needed to get her children away from him. Unfortunately she couldn't keep them safe, so she threw them into space and hoped for the best.

In the original timeline the Emperor would have killed someone for far less, so him sparing Erda was proof he cared about her. However in this timeline the Emperor fused with Slaanesh and became a new person. The Empress of Pleasure believed herself supirior to both her former halves in every way and wished to prove it by doing things they couldn't. The Emporer never told Erda how he felt, so the Empress was more then happy to do so.

She also told Erda that she would no longer destroy all religions, that she would enslave aliens rather then wipe them all out and would make sure humanity would have time to expres themselves since creativity gives her power. Erda didn't find the universe the Empress wanted ideal, but it was at least better then the Emperor had planned. Also joining forces would make her more likly to see her sons again so she reluctantly returned to the Empresses side.

During the crusade the Empress repeatedly tried to have sex with Erda however she refused every time. However she did fall in love with the Emperor, so it was only a matter of time before she did so with the Empress. After the crusade she had sex with the Empress many times and after all her son where found, she married the Empress. She was then give the tital of Queen in Black.

Erda was the second most powerful person in the Empireum only secoded by her wife. Many loved the queen as she was far **** then the Empress. She also did her best to help her children with they're many mental issues.

By the time the Empress was able to stand up from her chair, Erda had given birth to many new children that where adults by now. They would have been stronger then the Primarch's do to they're chaos god DNA but since the Primarch's where genetically altered for combat they're only compareble in power.

With Erda as queen, kindness and compassion may still thrive in the grim dark future of humanity.

(Empress of Pleasure POV.)

You just finished making some new laws when you realize something. Its been 4 days since you've fucked your wife. This should be rectified. You go into her office and see her doing paper work. "Hello my love, how is your work going?" You start kissing her neck. Erda groans. "Go bother the Custodes, I'm too busy." You rub her inner thigh and fondle her boob. "But your my favorite." She moans at your touch. "I better be. Fine, but only an hour this time." You smirk. "Then I better use every second to the fullest." You create the astral projection of Slaanesh to join the fun. Erda gives a dirty smile. "What am I going to do with you?"
