"You might suppose these creatures of fable are naught but a legend..."

The Inquisitor removed the cloth once masking his favourite device, its iron shining in the warm light of the hearth as embers cracked so faintly in the background. The thing was as crude as all contraptions made by humans - a mere piece of chiseled metal with a handle on one side and the Inquisition's sigil on the other. Simple, and older than their "emperor" himself, but the Poet knew it was devastatingly effective.
And she knew, without having the need to search within the human's eyes, that he loved the sound of the screams...

"Shadows of beautiful, slender profiles
that you might think cannot hurt your heart of steel."

The Eldar continued melodically while trying to prevent her body from shaking. The night was cold, and the sight of a brand put to flame wasn't precisely a sight of relief. Her brothers and sisters around were all bruised and damaged, yet their faces were proudly held high... These altered roles would not last long, humans were beneath them and it was the Eldar who should decide their feeble fates.
She looked at the little creature before her, preparing his primitive devices so he can bring her the most painful death he can conceive. "How crude!" She thought. "Artless, what lack of imagination!"
But then she opted to control hers thoughts, she was not to think as the Fallen Kin - she was a warrior of civilized means - her kills were clean and precise, and there laid the true art of destruction.

A deep breath, thoughts aside, she focused... Yes, he did not suspect a thing. He kept heating the iron at the fire, happy as a child with new toy. She decided to go on with her monologue - after all, the climax had to be perfect, and she needed to guide the emotions with her expert hand: the build of expectation, the shattering of illusions, the final prestige - the prestige... For wasn't she Sehnehviir the Poet? Guiding a mind with carefully structured verses was in her very nature.

"But in the dawning of a second..."

She made a pause, turning her head sharply to meet the Inquisitor in the eye as the man came near with his red-hot weapon, the brand now craving for her flesh.

"Our warriors come like a whisper through the forest,
and strike with blades as keen as verse!"

Her tone had the taint of joy and a challenge, the Inquisitor laughed with his deep, almost inaudible voice and aimed the iron towards the Eldar. "You sound very confident, Xenos scum. Do you not realize the situation you are in?"
Sehnehviir laughed back, a psychic emanation told her that the time had arrived - act two had finally begun, the illusion of control - she could see in the human's expression - had vanished. He was now questioning if he was safe, if the creature before him was the one at odds at all.

"So rest peacefully, warrior of mankind,
for we are only a sepia nightmare..."

The Inquisitor attacked the Eldar with the pitying eyes just as the wall behind her exploded in organized derby, falling downwards instead of inwards not to hurt the prisoners inside. Stunned, he turned just to embrace a blade within his stomach, then fell to his knees.
Confusion overrun his senses while bolters fired at the distance and the warcries of unimaginable opponents clamoured the air... How? His fortress was unbreachable.

Aspects raced past the deadly wounded human and deeper into the building, ignoring him like a fly. Only a pair of bare delicate feet stopped before his blurring gaze, and without raising his stare, he knew it was that Eldar witch.
Feeling his humiliation in her psicho-senstive hands, she felt the climax of her prestige throughout her alien body - it had been an elating rescue mission, masterfully-executed by the Warhost.
But the play was not yet done - not quite! She brought her lips close to those ridiculous round ears and whispered the Great Finale:

"We are a phantom that never came, never existed...
But left these crude walls stained with your blood. Sleep now. Shh..."

As Sehnehviir withdrew the blade upon his abdomen, he Inquisitor felt the most terrible pain... But his mind could barely process it. His last thought wished the Eldar's breath returned - death was so cold, cacophonous, there were Eldar everywhere. He fell forth and banished into a dark place.
Where the Eldar, the iron and the fire were no more...
