Masque notices the Emperor. but who is it?

Within seconds, the warp demon's form was changing. The extra pair of arms began to liquefy and merge with her back. The formerly androgynous features became more feminine and her right breast began to grow. It wasn't long before a woman in an indescribably decadent and beautiful dress stood in the darkness of the room. Hiding her face behind a mask, the creature walked to the window. It was almost as if the monster danced around the room and only when it stood in front of the window did it pause.

"Amazing!" sounded a voice as sweet as honey as it realized that it was no longer in its time.

Time. A material phenomenon. Something that did not apply to "the Masque." She had once been one of the highest, the fiercest and the most loyal servant of Slannesh and had been the closest to the throne. Yet now here she was. Dancing, seducing, playing and fucking whomever she wanted. Slannesh had banished her and yet it was the essence of the Princess of Perversion that drove the Masque. Amazingly, it was hard for her to feel her master at all. It was as if he had not even been born yet. And yet he was there.

Masque did not find this incomprehensible in the least. Of course, Slannesh had always been there, even before he was born. How could it be otherwise! It was he who had corrupted the Elder so that they could bring him into existence in the first place through that very perversion.

"What a ridiculous concept this time is!" smirked Masque, then danced over to the new Admiral's massive bed. "Vanessa, then? What a beautiful name." Breathed the higher demoness into the sleeping human woman's ear. "Be PROUD!"

These simple words would be enough for the human woman to recognize the brilliance of Slannesh.

"While I'm here! Should I ..." abruptly, however, Masque froze. An irrepressible, almost incomprehensibly powerful presence reached her. A dormant power that was not yet aware of its own mightiness. Even her seemingly endless dance was thrown out of sync as the ancient demoness sensed a creature lurking in the world below, so powerful that she would put it on a par with even the Prince of Perversion.

"No!" hissed the demoness angrily. "It is more powerful! How can that be? What..." Suddenly sei froze. "Should that be possible? The emperor of mankind?"

Uncertainly and only slowly returning to her beat, she danced again to the window and stared at the blue sphere below her. Several huge land masses were visible, one of which was shrouded in a huge cloud of smoke. Slowly, Masque tilted her head and narrowed her eyes. Should this be possible? Had she really traveled to the world of humanity's origins? To the cradle of humanity in a time long before the empire? The fact that her master had not yet been born indicated that, but she had never thought that it was so far in the past.

Demons perceived the material world differently, and Masque was a servant of Slannesh, not Tzenntch. She was interested in such trivial things as history.

"What interesting options!" she grinned, looking around. Hastily she drew an eight-pointed star on the window and breathed against it. Immediately she felt the warp being drawn to this sign and with a snap of her fingers she found herself on the planet below.
