Humans caused quite the stir when they first arrived on the citadel. Outsiders with talking beasts that hardly left their sides. They eyed the citizens of Citadel space with looks that both spoke disgust and distrust, and their whispers pronounced them demons. Their animal companions either shrank in fear or snarled with hackles raised, their lips moved and each pronounced. Soulless.

He could hear himself wheeze, breath scraping through his lungs like sandpaper over rough stone. Air was leaking from his helmet faster than the ruptured life support system could fill it, and the sound of sucking lungs in his ears was enough to tell him how long he had. His limbs flailed and shook, and he tried to patch the splits in the tubing but it wasn't working it just wasn't working.
His mouth opened in a scream, a single name over and over until the air entirely departed from his helmet and the pull on his body and the pain in his heart grew too much for a split soul to take and the man known as Shepard departed from this world and his Daemon still trapped on the corpse of the Normandy burst from her form into a miniaturized galaxy of Dust.

The 314 Incident was fast but brutal. Most fighting took place between ships, but the contested colony of Shanxi was where the two species met face to face for the first time.
The Turians with their advanced armor and weaponry lead a slaughter, in their ease of killing they hardly noticed how the new alien's beasts evaporated before one's eyes with the passing of their humans.
When the fighting settled down, the Turians and the Humans got their first good look at each other. The humans hugged their animals close, and stared pale faced at the tall crested creatures.
The Turian commander sent a report to Turian High Command, noting, Each Human is accompanied by an animal, the type and breed seems random. The creatures do seem to possess intelligence and the ability to speak, High possibility of extensive genetic modification on the animals of their planet. Best ensure restriction placed on more genetic modification experiments in this races future.
They never would have guessed the truth.

Cerberus did their best in putting him back together, but no one, no doctor, or holy man, had ever been able to turn loose dust back into a Daemon. This for a long time was a fact that burned holes in the back of Miranda's mind.
She could restore bone, muscle, even brain tissue, but restoring a soul, even a perfect woman couldn't do that.

The peace talks between the Humans and the Council were long and rough, the overwhelming force of the council ensured they got the best end of the deal. There was one thing however the humans were unwilling to budge on.
No being is to touch, talk to, or interact with a humans Daemon without the humans express permission.
They would not explain why.

By the time Shepard had joined the military after living out his childhood in the slums of earth, The Council had been informed of what exactly a daemon was, and why it was entirely prohibited to touch them without permission.
Tensions regarding the apparent soullessness of the races of the Citadel had died down once humans came to the conclusion that their souls must reside within. (The poor unfortunate beings, to not know the joy of one's own soul)

There are plenty of pictures of Shepard Daemon. This is a fact that drives Miranda's research into the thing that can't be done. She has studies pictures of the daemon from Alliance profiles, dossiers of the Illusive Man himself, even candid shots taken after Shepard was proclaimed savior of the Citadel. She researched all she could about known factors of Dust and its collection to no avail.
She doesn't know why she is as disappointed as she is. Even the Illusive man wrote off the recovery of the daemon as impossible.
