Pollock was born in 2013 or 2014 outside of the Chamber's borders and was raised by his deranged mother, Phina. As a young boy Pollock suffered near constant abuse and derision, particularly in regards to his disfigured wing. He grew up a fearful, submissive and anxious boy. When he finally parted from Phina, he was an introverted, aggressive young man.

Once he discovered the ways he could use his capacity for invisibility (he first learned of his powers as a newborn, and used it often when left alone to conceal himself), he grew slightly into himself, his transparency giving him temporary feelings of invulnerability and power. He spent much of his early adult years slipping through the world unseen, observing things he should not have, and thinking unclean thoughts. Isolated and angry, Pollock found peace in nothing (not even the discovery of his dead mother at the Beach), the palomino stallion was living in limbo until one day the unthinkable happened.

Pollock was transported to a parallel dimension, perhaps. Or an improbably physical and lingering dream world, wherein he woke up suddenly a young human teenager with a dislocated left shoulder. Elliot, he seemed convinced, surname: Pollock. The 16-year-old was confronted by the Grinch, who invited the boy to join him in saving Christmas and returning it to family from commercialism. The young man rebelled against the notion, his disdain for his mother alive even here, and joined forces with Santa Claus and his elves. He battled through throngs of gremlin-demons, troops of the Grinch, until transported finally to the doors of Santa's Workshop. Having been bitten in the thigh by a demon earlier in the night, the elves rushed him in to a safe room in order to try and stop the spread of the malicious venom. But while trying to heal him with light magic, Pollock's true self repelled the spell, and co-opted it — sucking the life from the elves, a natural corruption from dark magic, and eviscerating them.

Suddenly, the boy found himself teleported to the Grinch's side, the green man having felt his ripple in the dark force, and he agreed to take up sides with the Grinch, understanding there would be consequences for killing the gremlins. Whilst accepting his deal, Pollock found out what the Grinch was truly after. Not to save Christmas, of course, but to take over the North Pole and the powerful magic within. Pollock became hungry for this power, symbolized in a ying and yang, halves of split magic — dark and light. Pollock was imbued with powerful dark magic, and the Grinch healed his demon bite and granted him wingless flight (he failed to be able to control it, grounded even here). He realized he needed to try and create an army himself, animating broken toys coming from machines in the workshop, hoping first to overwhelm Santa's side, and then overwhelm the Grinch himself. But when it looked as if the fight was on the Grinch's side, his blind greed and anger overcame his senses and he returned to the Grinch, hoping to kill him while his back was turned.

But the Grinch was not stupid, and even more powerful than the boy realized. The Grinch knew his heart, and returned the venom to his body, rebroke his left shoulder, and was poised to kill the traitor. And then quite suddenly the light magic grew back in strength, calming the animated toys and destroying the balcony Pollock had ascended to face the Grinch. The hairy, green man was felled, and while falling, the boy tried once more to grab for that piece of magic, taking in his fingers a pulsing sliver...

And then he fell through dimensions and time, down through space and into familiarity. When he woke up, in the Forest, he had changed — horns and cloven hooves, a thrum of dark and frightful power, and a new tingling in his muscles. He was better than ever, enhanced with the physiology of the demonic gift-giver. He experimented with these gift first on females. Having found new confidence in himself, being able to approach the objects that once made him incredibly uneasy and cowardly was an incredible revelation to him. In fact, his confidence was well beyond that — Pollock now thought of himself as something of a demigod.

Shortly after recovering, keen to test other aspects of his new abilities, Pollock came across a group of horses exchanging pleasantries, and like many times before, was compelled to create some chaos. And so, in the guise of his invisibility, he watched Demian, Hestia, and eventually Kryten, until he was ready to make his move. Using his enhanced speed, Pollock ran Hestia through, fracturing her skull and causing a traumatic brain injury with his horns, ending her life — his first written kill. Hestia would come back, for a time, and haunt him, but in the end she regained ehr life and he learned, for the first time (though not the last) that death is not a dead end. After Hestia, he set off and came across Syntyche, the result of which would be his first get (estranged), Falk.

He tested the mettle of his ability on many: Elve, Rapt, Lirren, Malis. These horses now hold places of importance in his mind — like trophies, in a way, as each helped grow him into the man he is today.

His next victim would be Astri, in February of 2016, who he killed, as he had become accustomed to doing, in the Forest. he had, in fact, taken up 'throne' n the woods and had begun to adorn it with these pretty things. Blood lust, now that he could spill it much easier, consumed him. His third victim would be his most precious to date. Malis, a mare he had met before, briefly passing by in the night, would find him again nearby Hestia's corpse. Unable to get her to give him his name, and tired of her provoking, Pollock raped and killed Malis, leaving her there to join his jewels in the Forest. Not long after, he reunited with Lirren, one of the first horses he had tested his fear on, and they consummated their twisted little thing.

When Pollock returned t visit Malis' corpse, she was gone and he was thrown into a long period of obsession.

In Feburary of 2016, a busy month indeed, war was rumbling beyond the Forest, something Pollock would normally have little interest in, were it not for his second encounter with Demian. He came across the man, waling in pain and on fire, and was content to watch him die when until the fire calmed down and Demian turned to speak with Pollock — he invited him to make his mark in the war, in the 'name' of the Valley, and Pollock needed little more to get him aroused. He made his way to Desert, undefended as both monarchs were waging war in the Chamber, and slayed Nyxia, leaving her in the sand and thus his fourth victim (and, as it would turn out, his third to cheat him out of a victim — Nyxia would not die, but be saved by the subconscious of her unwilling mother).

Unbeknownst to him, Lirren conceived a boy, named Giver; Malis, whose body underwent the painful process of healing itself, carried a girl, Alight.

His last labor before the Reckoning were his encounter with Etro in the Forest, who he found weakened and mentally unhinged, the mare could siphon his power and provoked the ire of the gift-giver. He attacked her and left her, it would turn out, pregnant with a son: Bruise. He also tried to take Forlorn Forest, having just been left by the slain Tarnished. In the redwoods, he was reunited with Sinew, who he had met as a bold and tantalizing filly years ago — then, the world began to shake, and the Reckoning came.

Pollock woke up, as many did, on the Mountain. Upon descent, of course, he found himself once again a weaker man — no signs of the beast, no fear, adorned with a large, glossy pair of wings, a gift from the vengeful goddess. Pollock, however, was used to being an unmade man, and set his eyes on regaining all that he had built, ever resentful that Beqanna had taken back that which she had no claim over. He reunited, again, with Sinew, who showed loyalty to him even after seeing him naked; he would also, fatefully, meet Bruise, who toddled down from the Mounatin where Etro had birthed him, thinking his mother dead or otherwise unwilling to rise. Pollock took Bruise under his wing, together, they found a champion in Carnage, who assembled a team of those who would not bed the knee. The god-king used disased magic to try and recreate the Valley. In stead, he created Pangea, a desolate, barren wasteland where a beautiful valley once lay.

Pollock stayed and in time, he began to see how he could make such an ugly, sterile place home.

After a short time, Carnage decided to be rid of the earth again, and he called upon the kingdom to decide what to do when he is gone. Bruise, having had an encounter with a fairy who reinstated his krampus power, restored his father's powers and Pollock put his bid in for the crown. Uncontested, Carnage let him the throne and shot off into space. Pollock became king on Pangea, where he grew lazy and distant for a time, consumed by thirst of his dry spell — it had been far too long since felling Nyxia; he missed feeding the Forest bodies. After months of isolation and thinking, pacing the hinterlands of the waste, Pollock returned with renewed vigor, with plans to make the wasteland beautiful again. Ohio came to him in his time of need, and from her felled body sprang an oasis, cool and rimmed on vegetation. A part of Pangea, it seemed, had been willing to take blood but a much larger part still contained the willfulness of her birth mother. Not long after Pollock invited Pangeans to feed the earth with sacrifices, Pangea became victim to the fickleness of Beqanna. She disappeared. Pollock was throw from her western shore into the ocean and washed up near the Plains. From there, he set off back to his Forest to take back his throne.
