Retconjuration is a theoretical school of magic and one of the three disciplines of the Magic class Naughtymancy; it is aligned with the axis of Numbers and composed of the two elements of Motion and Matter. Erf-b1-p038a
No ordinary caster can practice it; there are no Retconjurers in Erfworld. It is reserved for the Titans. They don't like it much and use it as seldom as possible.
This school of magic allows past events to be changed to mesh with current needs. It is theorized that only the Titans have access to the powers of Retconjuration as it is too powerful for a mere mortal to comprehend even its smallest of ramifications. Being a very volatile subject, it is usually avoided in most public forums and viewpoints on the subject differ greatly.
Mortal users of Retconjuration would be in position to engage each other in a war of existential reconstruction, up to the point that only a timeline where they were all erased would be stable. Of course, as there have been no mortal Retconjurers, then either this is impossible or it has already happened.
(Alternatively, it may be possible that there is one Retconjurer far in the future, who managed to remove all the others except him or herself.)
Things that have been Retconned
The school of Retconjuration is notable for being an example of itself; the Numbers axis of Naughtymancy was an entirely different school called "Deletionism" the-ultimate-naughtymancy until the Titans realized that Retconjuration would be necessary for them to properly maintain Erfworld. As a removed school of magic, this also kind of makes Deletionism an example of itself.
Compared to the webcomic, Erfworld's Volume 1 book has a number of changes (which may be considered a sort of Retconjuration), as listed on the wiki page Book 1 Print Discrepancies.
Rob Retconjured all black/brown dwagons to purple for the book printing. Story below:
- When it came time for Rob and company to design the Real World dwagon plushies, the total number of colors initially came to seven. Pink, red, blue, purple, green, yellow, and black. Rob didn't really want to make seven different colors of plushie, because it's an odd number and it just felt like way too many for a set. This led Rob to see if he could get away with dropping one color of dwagon. After looking, Rob found that black (dark brown?) dwagons had only appeared once or twice, and never in combat. Furthermore, he thought black material would look bad with the embroidered eyes. A little while later, in the webcomic The Order of the Stick, a dramatic story moment occurred: many, many black dragons (not called dwagons in OOTS) from all over the planet were instantly wiped out by a spell. Rob considers OOTS to be sort of Erfworld's godfather comic; this led him to the conclusion that the same spell must have killed off Erfworld's black dwagons. This prompted Rob to Retconjure all black/brown dwagons to purple for the book printing. (Note that nothing was said about Retconning them in the webcomics, and some readers have reported still finding brown/black dwagons in the book.)
Also of note is that immediately above (following the word 'printing'), there is a link where Rob and Xin both recount and illustrate the above story. Currently, it is only correctly visible by those who pledged to the 2012 "Erfworld Year of the Dwagon" Kickstarter.
The Arkenshoes were originally silver, but retconned to be ruby. In the book the Wizard of Oz, the shoes are the Silver Slippers, but changed to Ruby Slippers for the famous movie.
When writing LIAB Epilogue 08, Balder forgot which revelation he had been intending to reveal, and thus repeated the revelation that Decrypted can turn. He replaced it with the revelation that Wanda can use an Archon's natural Thinkamancy to see through their eyes.
LIAB Epilogue 25 was first released as a video, and showed Archons in the Charlscomm capital glowing an ominous red. Forum speculation quickly went rampant that Charlie had analyzed one of the captured decrypted units and figured out how to decrypt his archons so that Wanda would be unable to uncroak them. The glow was quickly retconjured to blue.
A klog initially stated that captors payed a fugitive's upkeep. This was later changed to be consistent with IPTSF, where Jillian had to forage her upkeep to avoid automagical capture.
Hvs.tCF 33 originally showed the Jetstone radish on the garrison building of Spacerock, despite the fact that it's Signamancy should have switched to Gobwin Knob due to having been conquered. This was later switched to Stanley's livery.
Hvs.tCF 43 had Parson state that the Spacerock was now a level 4 and that Sizemore was using his juice to make improvements each turn to lower the cost of bringing it back up to level 5. Hvs.tCF 51 contradicted this by having Sizemore be depressed about the city not having his personal touch as Parson auto-magically upgraded the city back up to level 5 the turn after the battle while everyone was still in the Magic Kingdom. This was again contradicted by Stanley who said the city was level 4 on Hvs.tCF 71. Due to the discrepancy, Hvs.tCF 51 was retconjured to state Spacerock as a level 4.
Hvs.tCF 66 originally had round necklace on Bunny rather than triangle, an incorrect shade of orange on the bag (fixed to be more saturated) and a different interior of the portal room (changed to be in line with the image from Hvs.tCF 140). The necklace was also later fixed on other pages (this includes Hvs.tCF 67 and Hvs.tCF 76).
Hvs.tCF 113 originally had Lilith throwing the corpse through the portal with many, subtle motion lines that could be incorrectly interpreted as if the portal is sucking her in. It was later retconned to a simpler, more obvious set of lines.
Hvs.tCF 118 originally had a Maggie visible in the second panel. This was later fixed to have her properly veiled.
Hvs.tCF 119 originally had the close-up pane of Maggie's pendant display an omega symbol. This was later fixed to display an eye.
Hvs.tCF 128 originally showed Wanda without the Arkenpliers. This was quickly corrected.
One line of fan speculation postulates that there could be a Retconjuration war going on between the Titans, with one faction backing Stanley the Tool's bid to overthrow royalty and unite the Arkentools, and the other opposing it. So far, the side opposing Stanley has left an extra gem in a Marbit mine, leading to Stanley's defeat at the Battle of Warchalking, and the other has caused Lookamancers and Findamancers to research the "Summon Perfect Warlord" spell, or possibly provided Parson's glasses, bracer and sword, leading to the defeat of the Royal Crown Coalition.
Real World References
The name refers to "retcon", short for "retroactive continuity", in which the history of a fictional setting is changed after publishing to mesh better with the current desires of the author. Ironically, Retconjuration is itself the product of a retcon; the Naughtymancy class previously aligned with Numbers was known as "Deletionism" before it was replaced with Retconjuration.
