Karn, Silver Golem had been thinking. About Mirrodin. And about how it had become New Phyrexia. He thought about feelings.
Karn finally decided that maybe he should do something. He told Ugin, the Spirit Dragon that he was going to New Phyrexia to look at it, and think about some things...
When Karn finally got around to checking in on his own creation, he was faced with a reality that he had not thought about, despite all the time that he spent thinking.
Karn had expected the typical Phyrexian flavor of what had previously been his own Mirrodin. However, he arrived to a place that was devoid of anything, except the faint hint of a horizon. It was similar to his original idea for the precursor to Mirridon, Argentum, in that there was nothing here. Karn had spent a lot time thinking about Argentum, and it had been his magnum opus. He thought about feelings.
Then Karn started to think again. "Nice place" he thought. "I thought there were supposed to Phyrexians here" he thought.
Karn decided he would take a walk, to clear his mind, and think about things.
Karn traversed the void of his mind, and his new surroundings, for days, weeks, and months, through a landscape without form, color or sound, under a sky of nothingness, a nothingness that, once Karn considered it, was no longer nothing, which the nothingness of this world then also consumed. It felt familiar to him.
Aside from seeing his own body, and a vague sense of gravity, the only other point of reference Karn had for his own existence was the dust-like quality of the void, which swirled like a mist, or a super-fine powder, as he moved.
At some point, Karn thought that he would stand still for a while as he was thinking. Eventually, he noticed that the dust had started to move around him, even though he had been still for a long time. It was a breeze, a sign that somewhere, there was something else.
The breeze became a steady wind, and in what might have been the distance, Karn percieved an irregularity, an amorphous shadow in the dark, neither far nor close.
As Karn was thinking about this, the gentle swirling of the fine dust whorled into a cyclone around Karn, and he thought that he might have what might be a feeling in his mind space.
Then suddenly, all the dust around Karn was sucked away, revealing a glistening, geometric lattice beneath his feet, and all around him. At the edges of the dust cyclone, Karn could see large shapes, and the flickering, writhing shadows of what looked like tentacles.
Then, in a crackling flash, the dust, and somehow reality, shattered, and Karn saw before him three figures which seemed infinitely large. Karn could not tell where they ended, or where his reality started.
Karn thought about how this whole situation reminded him of something that he thought that he had heard the Gatewatch talk about. "Hm, Eldrazi", Karn thought.
Ulamog, the Ceaseless Hunger and Kozilek, the Great Distortion transposed themselves into Karn's perception, tearing at his existence, as Emrakul, the Promised End attempted to process Karn's mind, but that was a lost cause. Karn tried to summon the metallic ground beneath him to his aid, but there was nothing. The ground was not metal. Although Karn could see the jagged, regular, crystalline chrome beneath his feet, it was nothing. The dust was nothing. The Eldrazi were nothing. Karn, was nothing. Emrakul and the other Eldrazi did not need to distort Karn's mind in order to ingest him. Karn's mind, was nothing.
Now it wasn't unusual for years to go by without hearing a word from Karn, Silver Golem, but Ugin, the Spirit Dragon kept thinking about him going to New Phyrexia, and kept thinking that if something bad were to happen to him, it could be a long time before anyone knew, since Karn was usually M.I.A. anyways. So, Ugin decided that he would just go check in on New Phyrexia too, and see if everything was okay.
Upon arrival, Ugin realized immediately that the Eldrazi had completely consumed New Phyrexia. How they got here he did not know, but he knew this was bad, real bad. He also knew that the Edrazi would already be aware of his presence as well, and before he had finished that thought to himself, the fog of dust surrounding him became a screeching vortex of distortion. Without hesitation, Ugin engulfed himself in Ghostfire, as his colorless magic was strong against the Eldrazi's void magic.
The three titans now stood around Ugin, three points of a triangle with Ugin in the center, alight in ghostfire. Ugin knew that the Eldrazi were much stronger here, and now, than they had been on Zendikar, as they had already consumed the entire plane, as well as the power and energy of all the phyrexians. He also knew that they were hungry, as there was nothing left here. Ugin could not planeswalk away, as the titans were distorting the nature of reality around him, and were it not for the ghostfire, he would already have been twisted asunder. Ugin did not know if the Eldrazi had feelings, but if they did, the ones they held towards Ugin would not be pleasant. Ugin thought he could sense anger, or something like it, in the intensity of the Eldrazi's presence, and although his ghostfire would protect him for now, he alone could not fend off an all out attack.
Although the Titans had Ugin trapped, and were trying to penetrate his ghostflame, they were not approaching him. As Ugin was contemplating why this might be, he started to hear an irregular, metallic beat, like dozens of enormous, muffled bells, echoing through the a canyon in the haze, and as the sound grew closer, a metallic tinkling, and scratching, and whispering. From between the three Titans, came marching enormous conglomerations of Phrexian behemoths which had been twisted and defiled with the maddening chaos of the Eldrazi. Apparently the Eldrazi had not devoured everything here, and had kept some of the most hideous and terrible Phyrexian abominations to further warp in their own twisted way. These Phyrexian Eldrazi did not stop marching, and continued directly towards Ugin. Now, Ugin would be forced to fight with these colossuses as the Titans stood at a distance, continuing to try and diffract his ghostflame.
Ugin could not hesitate any longer, and in a blazing colorless infero, he charged at the horrible beasts. Ugin's blasts of ghostflame sent masses of writhing flesh and splinters of metal flying. But the goliaths were not deterred, as the blasted pieces of themselves came crawling and slithering back together, and soon, Ugin would have no place to turn. As Ugin fought desperately to create space between him and the Phyrexian Eldrazi, he realized that he was still not even fighting the Titans yet, while their influence on him was growing stronger, refracting and dimming his ghostflame, and exhausting and cracking his mind.
It would be futile for Ugin, for as he was pummeled, and his ghostflame extinguished, his mind and body would be warped and shattered, and he would succumb to the Eldrazi. Much like they had used their Phyrexian Eldrazi Conscriptions against Ugin, the Eldrazi would now use Ugin to prepare the next plane that they were to devour, quelling any would-be resistance ahead of their arrival.
He had become, Ugin, Eldrazi Harbinger.
Turns out, the first place the Eldrazi wanted to go next was Strixhaven, to learn a few lessons and hang with their old bud Wandering Archaic
