Per Rob on August 19th, 2009:
I am going to make a more drastic change. A change to the magic table. If you now look at Klog 2, you will see that the branch of magic I called "Deletionism" is no longer there. It has been deleted.
In its place is a new branch of magic: "Retconjuration." (The name was also Rich's idea.) This is a theoretical branch of magic, like an undiscovered element on the periodical table. No ordinary caster can practice it; there are no Retconjurers in Erfworld. It is reserved for the Titans. And I can tell you, they don't like it much and use it as seldom as possible. I apologize for invoking it now, especially to the wiki editors.
So, any differences you notice between the printed book and the old archives you can chalk up to Retconjuration, the ultimate form of Naughtymancy.WoT-8/19/2009
 Speculation from the page
- May be a reference to "Chainfire," from the Sword of Truth series by Terry Goodkind. "Chainfire" is a mental magic that changes people's memories to accommodate for the fact that Main Female Character Who Is a Major Political Figure's actions never happened, as that person never existed, even to themselves. Of course, this has the unfortunate effect of wiping out various sections of memory for varying people, bringing about The End of the World, unless Main Male Character does something. Also, balefire from the Wheel of Time series by Robert Jordan.--BarGamer 18:37, 20 August 2009 (UTC)
- Retcon stands for Retroactive Continuity. It's used to fix continuity screwups that have already been published or aired (Soap Operas are notorious for this and have been for decades). Of late, it's been used in various games to fix old lore to match wanted game mechanics. Anytime something doesn't line up with original backstory and the author writes something to dismiss why the old stuff might have been a fact. One example I can think of is the 2nd Jurassic Park book where the paleontologist in it refers to something a paleontologist in the first book said as fact and dismissed it as bad science. It's also an amnesia pill in the BBC series Torchwood which is named after the whole Retroactive Continuity thing as a joke. --Ichthus (eyeBook) 21:27, 20 August 2009 (UTC)
- Any use of time travel that may or may not be introduced in Erfworld as chronomancers would, in essence, be a form of Retconjuration, as one travelling to past turns would have the ability to change it. Thus, would not the ability to move the entire world one turn foward as seen in LIAB_21 have been a form of reverse Retconjuration? This can happen only if Vanna was linked to both Charlie and the Arkendish to gain access to a Titan only ability Valareos 22:29, 28 May 2011 (EDT)
 Element and Axis
Deletionism is Naughtymancy, the magic of Motion and Matter, and the abscence of Life. It is aligned to the axis of Numbers. How Deletionism manifests is as yet unclear, but it could be the Deletion of Life, or of Numbers, or the use of moving matter to "delete" life. Commander I. Heartly Noah June 3 2009

Hm. Is a prequel a retconjuration? Abb3w 18:09, 26 November 2011 (EST)
- Unless it the author decides to change something in the subsequent parts because of something in the prequel, it is probably not. We can call it a flashback. :) --Muzzafar 02:33, 27 November 2011 (EST)
