Lore & Story
Phyrexia, Explained
One faction, three invasions, across thirty years of Magic's story. Where Phyrexia came from, why five praetors could not agree on what it should be, and how it very nearly ended the Multiverse.

Origins Under Yawgmoth
Phyrexia does not begin as a place. It begins as Yawgmoth, Thran Physician , a physician on Dominaria during the Brothers' War era who turns to corrupting his own body after his ideas about "perfecting" flesh get him thrown out of Thran medical society. Exiled underground, he keeps going. The important thing to hold onto here: Yawgmoth was never a planeswalker. He is a person who made himself the god of a plane, ruling absolutely over the twisted, half-mechanical world he built out of whatever Dominaria's underground had to offer.
That plane is Phyrexia, and for millennia it exists as effectively a weapon pointed at Dominaria, built and refined with nothing else to do. When it finally launches - the Invasion, told across Invasion, Planeshift and Apocalypse - it very nearly succeeds. Urza Planeswalker, who spent three thousand years preparing exactly for this moment, dies before it is over. The Weatherlight's crew is spent almost to the last person. Dominaria survives, but only barely, and Yawgmoth himself is destroyed in the process.
What is left afterward matters more than the defeat. Karn Liberated , a silver golem Urza built centuries earlier, becomes a planeswalker in the invasion's aftermath and inherits what remains of Phyrexia itself - a broken, leaderless plane that nobody else wants. He does not do anything with it right away. That inheritance is what the next section is about.

New Phyrexia Rises
Karn eventually builds a plane of his own, Argentum, better known by the name it takes for most of its life: Mirrodin. He has no idea that he is carrying Phyrexian oil on his own body, a remnant of the plane he inherited, and that oil seeds itself into Argentum the moment he arrives. For centuries nobody notices. The oil is patient in a way nothing else in Magic's story is.
Scars of Mirrodin is the slow-motion answer to what that oil was doing the whole time. It spreads, it corrupts, and by the end of the block it wins outright - the plane falls, and what used to be Mirrodin becomes New Phyrexia. Same plane, two names, and the second one sticks.
New Phyrexia does not emerge with a single leader. It emerges with five, one per color, each convinced their own vision of Phyrexia is the correct one:
Elesh Norn, Grand Cenobite ↗
White. Wants a Phyrexia of forced, engineered perfection, and eventually wins the argument at home.
Sheoldred, Whispering One ↗
Black. Wants Phyrexia to go back to being what it was under Yawgmoth: cruelty as a first principle.
Vorinclex, Voice of Hunger ↗
Green. Growth and consumption with no direction beyond more of both.
Jin-Gitaxias, Core Augur ↗
Blue. Treats perfection as an engineering problem to be solved by data and dissection.
Urabrask the Hidden ↗
Red. The one praetor who does not want to invade anywhere, and hides from the other four for it.
That disagreement is the whole reason New Phyrexia does not invade anywhere for roughly the next decade. Five gods of five different colors, each certain the other four are doing Phyrexia wrong, spend that time consolidating at home rather than looking outward. When they finally do agree on something, it takes one of their own number turning the disagreement into a plan.

Compleation and the Invasion of the Multiverse
Not to be confused with the Invasion above. That was Yawgmoth attacking one plane in roughly 4205 AR. This is Elesh Norn, Grand Cenobite attacking every plane at once, across 2022 and 2023 in real-world publishing - the same faction, the same name for the event, twenty years and one dead god apart.

What makes the second invasion possible at all is compleation. An ordinary Phyrexian conversion turns a victim into a monster with no way to travel between planes - which is why Phyrexia had stayed contained to its own worlds for so long. Compleation is different: it converts a planeswalker while leaving their spark intact, so the result is a Phyrexian who can still walk between planes on their own power. Elesh Norn's whole strategy depends on this one trick. Without it, Phyrexia cannot leave New Phyrexia at all.
Compleation is just Phyrexia's word for corruption.
It is specifically the version that preserves a planeswalker's spark. Every other Phyrexian conversion produces something that cannot travel, which is the entire reason compleation is the plot rather than a flavor word - it is the mechanism the whole invasion runs on.
The story shows what this looks like from several angles. Tamiyo, Compleated Sage , the moonfolk storyteller of Kamigawa, is the first walker shown compleated on the page, in a set where nobody yet understands what it means. Ajani, Sleeper Agent is compleated quietly and sent back to infiltrate his own friends, which is the entire plot the card's name gives away. Vraska, Betrayal's Sting is compleated in secret during the invasion's build-up, a fact her allies do not learn until well into the story. And Nissa, Ascended Animist is turned against the plane-life she had spent her whole career protecting - the cruelest version of the trick, because it uses what she already believed in against her.
The invasion itself arrives through Realmbreaker, a tree grown through the Blind Eternities - the space between planes - specifically so that Elesh Norn's forces can reach every plane in the Multiverse simultaneously rather than one at a time. It very nearly works. It is stopped in March of the Machine: The Aftermath, where Elesh Norn is defeated, but the cost is permanent: Realmbreaker's collapse tears open the Omenpaths, passages between planes that need no spark to use. Ordinary people can now travel between worlds Phyrexia spent millennia trying to conquer, which is the one consequence of this whole history still shaping every set published since.

FAQ
What is Phyrexia in MTG?
A plane built as a weapon. It began as the personal project of Yawgmoth, a Thran physician who corrupted himself and made himself its god, and it has invaded the rest of Magic's Multiverse twice: once as his own plane attacking Dominaria around 4205 AR, and once as New Phyrexia attacking every plane at once, roughly two decades later in real-world publishing.
Who are the Phyrexian praetors?
Five leaders who emerged when New Phyrexia formed, one per color: Elesh Norn (white), Sheoldred (black), Vorinclex (green), Jin-Gitaxias (blue) and Urabrask (red). Each wants a different version of Phyrexia, and that disagreement is why New Phyrexia spent roughly a decade consolidating before it invaded anywhere else.
What does 'compleated' mean in Magic?
Being converted into a Phyrexian while keeping your planeswalker spark. An ordinary Phyrexian conversion produces a monster with no ability to travel; compleation keeps the spark intact, which is what let New Phyrexia reach every plane in the Multiverse at once instead of staying trapped on its own. Several cards render it directly in their names and art, like Tamiyo, Compleated Sage.
Is Elesh Norn dead?
Defeated. She leads the invasion of the Multiverse and is stopped in March of the Machine: The Aftermath, at the cost of Realmbreaker collapsing and opening the Omenpaths. Magic's story rarely closes the book permanently on a praetor, and this page will be updated if she returns.
What's the difference between Yawgmoth's Phyrexia and New Phyrexia?
They are the same plane under two names and two very different regimes. Yawgmoth built the first Phyrexia and was destroyed defending it during the Invasion block. Centuries later, Karn - the planeswalker who inherited what was left of it - unknowingly seeded his own plane, Mirrodin, with Phyrexian oil, and that oil eventually took the plane over and renamed it New Phyrexia under the five praetors.
Which sets tell the Phyrexian invasion story?
Three separate chapters. Yawgmoth's original invasion is Invasion, Planeshift and Apocalypse (2000-2001). New Phyrexia's rise is the Mirrodin block and the Scars of Mirrodin block. The invasion of the whole Multiverse runs from Kamigawa: Neon Dynasty through March of the Machine: The Aftermath (2022-2023), and every set in that last group has its own guide on this site.
