I'm not that good at expressing this, so if you have any questions/comments/corrections/clarifications/glaring errors you would like to voice, I would appreciate it.
I think there's a deeper level to the Erfworld conflict than just the war. I think the Magic Kingdom is the driving force behind everything. Stanley's rise to Overlord, the Fall of Faq, Everything.
Their purpose? To bring about Peace, regardless of the expense.
There are several pieces of information and evidence that can be tied together to piece together how they did this.
One of the key pieces of this is Faq's Predictamancer. While this is pretty hazy, because we have yet to see a Predictamancer/Predictamancy in action, there are still several important points the predictamancer raises.
-Where are they? It's been stated that casters are valuable units and are normally captured/converted, but we haven't seen the Predictamancer anywhere on Stanley's side.
-Loyalty/Duty. A unit on a aside has a duty to inform their commander of things that will cause the destruction of their side. This is the point where things get especially fuzzy, since, as stated before, we don't know the specifics of Predictamancy, nor do we know which prediction came first. It is possible that the prediction for Faq's fall came before Wanda's, and if the predictamancer could see enough to know what wuld happen, it would conflict with their duty to tell Wanda
-The fact that the Gobwins rebelled when Stanley left is too convenient to be coincidence. However, as stated, loyalty/duty should prevent Stanley from setting this up. In addition, Wanda expected Stanely to lose when he attacked Faq, which implies that he would have trouble conquering Faq, and would have depleted his forces, which would make retaking Gobwin Knob difficult. It's true that units heal at start of turn, but there would still be a decent amount of units lost. Retaking the city wold be a bit daunting, and Stanley, if he had been the mastermind behind overthrowing Saline, I think he would have been a bit more cautious with those odds.
As for how this would attain peace, and why this was all necessary, the reason for this is the royal noble system. It's been stated that in addition to being stronger and levelling faster, nobles can occasionally break off and for their own side. As far as we know, this is a unique trait of royals, so the same issue will not arise should an Overlord conquer the world.
One of the indicators that the Magic Kingdom was behind this was the conversation between Sizemore and the Grand Abby, she seems to know a bit more about the battle for Gobwin Knob than she should have, and while this could be marked off as knowing what the spell would likely result in, or using Eyemancy to observe the conflict, the fact that she thinks Parson could make Peace in Erfworld a reality implies that it was part of a greater scheme.
Of course, given the response Royals normally have when a non-royal takes power, it would be a bit difficult to create this scenario, so they need a little edge, one 500,000 spell later, and they get the perfect warlord, one who comes from outside the game, and isn't limited by the mindset that's been developed since the titans built the world.
-The predictamancer is a member of/controlled by the Magic Kingdom.
-The predictamancer informs Wanda that she will become attuned to an Arkentool, whihc leads to her getting STanely to attack Faq.
-Banhammer asks if Faq will fall, and the Predictamancer tells him yes. Jillian gets popped.
-Jillian goes off an a mercenary mission, and Stanley invades. The Predictamancer escapes to the Magic Kingdom or vanishes through some other means to prevents inquiry about why this happened.
-Wanda, wanting to find her Arkentool, persuades Stanley to quest for the remaining Arkentools.
-Stanely croaks several royal units in his efforts to get the Arkentools, and the Royal Crown Coalition is formed.
-The Royal crown Coalition starts to conquer the other cities under Stanley's control, and his ability to fight back dwindles.
-Stanley is reduced to the capital city, and is forced into a corner, in order to salvage the war, he spends 500,00 to summon the perfect warlord, aka: Parson Gotti.
-Events proceed as in the comic.
-With Wanda's Decrypting ability nd the return of the Dwagons, plus the complete destruction of the RCC, Stanley's side is probably the strongest side in the nearby area. Charlescomm and Transylvito are probably the only factions without crippling losses.
-Stanley's forces begin reclaiming their previously controlled cities and acquiring the cities of the weakened sides in the area. (Probably the filler between end of Book One and beginning of Book Two)
-Book Two starts, with Stanley's side the dominant power in the region. At this point he is recognized as a significant threat and that his goals are probably world domination. Parson will be recognized as a genius tactician and will be accounted for when dealing with their forces. While still a dominant force, other factions will be aware of Parson's tactics and will try to mimic/account for them. The real war begins, since victory against other forces will be much more difficult.
So, what say you?
