Ati (Mistborn)

"I'm all around you—the air you pretend to breathe, the ground beneath your feet. I’m in that knife and in your very soul."

- Ati

"You realize the forces I can bring to bear against you, child? You realize the power I have, the destruction I represent? I am mountains that crush. I am waves that crash. I am storms that shatter. I am the end."

- Ruin to Vin

"This process we are engaged in, the end of all things—-it's not a fight, but a simple culmination of inevitability. Can any man make a pocket watch that won't eventually wind down? Can you imagine a lantern that won't eventually burn out? All things end. Think of me as a caretaker—-the one who watches the shop and makes certain that the lights are turned out, that everything is cleaned up, once closing time arrives."

- Ruin to Vin

Summary
Ati is the first Vessel of the Shard Ruin,

History
Ati originated upon the planet of Yolen and was a majour member in the conspiracy to shatter Adonalsium. After the Shattering he took up the Shard Ruin.

Post-Ascension
Following their Ascension, and Leras traveled to a rather empty solar system and constructed the planet of Scadrial out of their own Investiture. And created a deal, wherein Preservation would create the planet and Invest the humans that they created, and Ruin would eventually be allowed to destroy it. Though Preservation exploited a loophole and sealed Ruin's mind away in Preservation's own perpendicularity, the Well of Ascension. But at the cost of his own mind and body.

Ruin stayed within the Well for millennia, trying to escape and fulfill his end of the deal. Which he would do through various subtle manipulations. Manipulating text in order to trick the Terris people and Alendi into giving the power in the Well of Ascension to him so that he could be released. Only one was able to notice these manipulations, this being Kwaan, who noticed the discrepancies between text and copperminds, and his memories; and began to renounce Alendi and sent  Rashek in order to stop him from accidently releasing Ruin.

Rashek eventually ruined the chances of Ruin to escape, killing Alendi and taking up the power instead of using it to free Ruin. Leaving him to have to wait another 1024 Years.

The Final Empire
Over time he manipulated the mind of Rashek. Twisting him and making him more violent and erratic.

He came to choose Vin as his weapon, having her Snap during childbirth and having a Hemalurgic Spike with Bronze Allomancy in it in order to give her the power necessary to feel the pulsing of the Well of Ascension, and so that he could manipulate her mind so that he could use her to release him. He would also speak into her mind with the voice of Reen, taking advantage of her trauma and dependence, and working to manipulate her through it.

Post-Collapse
After the death of the Lord Ruler in 1022 FE, he began to slowly manipulate the Steel Inquisitors into committing atrocities across the planet. Though at the time they were yet to fully understand it.

During an unknown period of time before 1024 FE, he began to speak to Zane Venture, often egging him along to kill everyone around him. These manipulations of Zane ultimately did very little, for Zane simply believed himself insane and tried to ignore the voices in his head.

After Sazed found Kwaan's Inscription and made a copy of it to study, he began to manipulate the text in subtle ways so that Sazed, Vin, and the rest of the crew would be misled into releasing him. These manipulations would not be discovered until it was too late.

Trying to prevent Sazed from coming with the Mist Spirit to prevent his release, he sent Marsh to Keredik Shaw in order to stall, or even kill him.

She took up the power and release it, ultimately leading towards his release.

War of Ash
Following his release he began to slowly bring about the destruction of the world. With the Ashmounts erupting more ash to drown the landscape, earthquakes happening everywhere, and Koloss and Inquisitors taken over in order to wreck havoc across the planet. But, during the Battle of Hathsin, he was slain by Vin, who had taken up the Shard of Preservation.

After his death, the Shard of Ruin was taken up by Sazed, becoming intermingled and mixed with the Shard of Preservation to become Harmony.

Personality
He is said to have been a kind and generous man before he was twisted by the Shard Ruin, and his personality shifted the nature of the Shard from being pure destruction, into becoming mere entropy and decay.

While he wishes to see the destruction of all things, it is not out of hatred or evil, but in believing that death and destruction are inevitable and necessary parts of life and existence. As he sees it, the destruction he causes serves a creative purpose; without death, there can be no further life. And thus, he is not necessarily evil, despite his intentions.

If he had won, he would go beyond just Scadrial and try to reduce the entire Cosmere back to equilibrium.

Due to the negative emotional effects of the Shard he is holding, he is arrogant and prone to boasting. Along with this, he can be very manipulative to achieve his goals, caring little for who he harms or takes advantage of in his push towards escaping the Well of Ascension and bringing about entropy and destruction.

Powers and Stats
Name: Ati | Ruin, Herr (By South Scadrians), God (By Zane)

Age: Unknown | At least 11,000

Gender: Male

Classification: Human | Shard of Adonalsium, Vessel of Ruin

Powers and Abilities: Immortality, Limited Omnipresence, Teleportation, Time Manipulation, Precognition, Telepathy, Soul Manipulation, Limited Information Manipulation, Avatar Creation, etc

Immortality
He is ageless and immortal, having lived for thousands of years before he was killed by Vin holding the Shard Preservation.

Expanded Mind
As a Shard he has a greatly expanded mind, able to take in and process far more information than any other human could possibly even dream of. This also gives him a fundamental understanding of the Cosmere, and of things happening far beyond his sphere of influence.

Time Manipulation
All Shards are capable of bending and stretching time to their whims, minutes being described as years from the point of view of a god.

Future Sight
Shards are capable of seeing far into the future, well enough to make The Diagram look meagre in comparison.

The future is hard to see for Shards, or for any version of future sight, when faced with another being capable of seeing the future, and that the further one looks the harder it is to make out the future.

Omnipresence
He has Limited Omnipresence throughout all of the Cosmere, with particular focus upon Scadrial, where Preservation is deeply Invested into every single piece of it. Despite the Power itself permeating all things, his body and mind itself can only be in a limited amount of places at one time.

However, Ruin is capable of manifesting his body in multiple places simultaneously and act separately in each manifestation.

Information Manipulation
As a result of him being Invested throughout all of Scadrial, he is capable of fully manipulating text and information written down. This also allows him to manipulate the memories within Copperminds during the short period of time that they are within the mind of an individual.

However it does have a limitation in that it cannot effect the minds of anyone, and that it cannot change text that is written into metal.

Investiture
He has access to a effectively infinite supply of Investiture. As with all Investiture, whenever it is used it would be filtered back to the Spiritual Realm for him to use once again. However, it is finite

Telepathy
He is capable of manipulating the minds of those who have some sort of hole he can go through, primarily through those struck by Hemalurgic Spikes. He can speak into their minds in order to manipulate them. However, he cannot hear their thoughts. This manipulation can grow the the extent of nigh complete control over those with a sufficient amount of Hemalurgic Spikes, such as Steel Inquisitors, Koloss, and Kandra.

His voice can be so subtle that he can make people believe that it is their own thoughts, and he can manipulate people into becoming a different person, or believing things which aren't true.

It is not fully required for them to be pierced with a Hemalurgic Spike, as insanity alone has been shown as being enough for one to pierce through and communicate through.

Avatar Creation
All Shards are capable of creating Avatars

These Avatars can be spread throughout the Cosmere, but unlike Splinters lack full autonomy
