The Magic Kingdom is a location in, just outside, or sideways from/parallel to Erfworld. It appears to be an island of round shape divided into 8 sectors and with a round Portal zone in the center of it.Erf-b1-p011 Interestingly, the color of each segment continues out into the surrounding water. The effect is much like that of colored lights being projected out over land and sea.
The Magic Kingdom is the domain of casters of all types, who can interact with their counterparts from all around Erfworld in a community removed from the constant war and politics of the many warring sides. Casters from enemy sides rub shoulders with Barbarian casters, many of whom are permanent residents of the Magic Kingdom.
The number of sectors (eight) corresponds to eight major classes of Magic:
- green (possibly devoted to Hippiemancy)
- blue (possibly devoted to Stagemancy)
- yellow (possibly devoted to Clevermancy)
- purple (possibly devoted to Hocus Pocus)
- gray (possibly devoted to Spookism)
- teal (possibly devoted to Eyemancy)
- red (possibly devoted to Naughtymancy)
- brown (possibly devoted to Stuffamancy)
Portal ParkErf-b1-p011 is located in the center of the Magic Kingdom and has multiple portals that seem to lead to other, unspecified, locations. One of the portals is known to lead to the portal room in Gobwin Knob.Erf-b1-p013Erf-b1-p140 It is likely there is a portal connection to portal park in all capital cities, or at least the capitals of larger sides.
Portals are the only means of entry into the kingdom. The Magic Kingdom is only open to Casters. A non-Caster that attempts to enter the kingdom via a portal immediately disbands,Erf-b1-p134 as Queen Bea of Unaroyal did, immediately after sending all of her casters through a portal in her capital city prior. The moment Bea stepped through the portal, she disbanded, as did all her units (who were all outside the city), except the casters, who became barbarians.
All the permanent residents of the Magic Kingdom are Barbarians. They were either in the Kingdom or otherwise safe from disbanding when their capital fell,Erf-b1-p102 or they popped as barbarians. Given that some Warlords pop spontaneously, it's likely that a much smaller number of Casters do the same.
These resident barbarians survive by working for various sides by contract (as mercenaries, or selling spells as a service), selling scrolls for Shmuckers, or live in the kingdom selling services for Rands and trading those for rations and upkeep. Sizemore has mentioned that he has worked in gardens in the Magic Kingdom, so it's likely they also grow at least some of their own food.
Parson did not croak when he entered the Magic KingdomErf-b1-p140, implying that he is either a Caster or immune to the portal's disbanding effect. His stats contained an entry describing him as 'special', which might include either being a Caster or being immune to disbanding. His physical ability to enter aside, he is socially prohibited from entering because he is a warlord.

In the distant past, before there was a Magic Kingdom, war still raged much as it does today. Kingdoms rose and fell, their kings, queens, and overlords slain. When such a thing happened, all units outside the city would be disbanded, and those inside would wait helplessly for their capture or doom. Yet, sometimes an heir survived to live as a barbarian, perhaps to even one day rebuild their destroyed nation.
But strangely, one other type of unit managed to survive summary disbanding or neutrality - the casters. Most of them roamed the world as barbarians, unable to rejoin their defeated nation or be supported by the now poor or schmuckerless heir designates who struggled to even make upkeep for themselves. Some faded away or were captured, but many found enough work to survive on their own.
Then one day, a plan was hatched among two master-class caster barbarians, both of them friends by loneliness or necessity. They would make a haven for themselves, where they need not struggle for upkeep or wander the world endlessly. The Thinkamancer of the group linked with his friend, a Findamancer. Together, they found a Moneymancer and with him created the first portal to the Magic Kingdom, though then it was simply their haven.
It was a small island then, but rich in greenery and made to their tastes. Soon though, they realized the potential that their small haven offered. Linking again with his then paramour, the Thinkamancer found two others to help him. Together, the triad of Thinkamancers conducted the most powerful natural Thinkagram ever composed in the history of Erfworld - sending an open invitation to all wandering casters to join them and help build a nation of casters - a Magic Kingdom.
From all over Erfworld they came, the nationless and sometimes destitute, all to help in the creation of this grand project, this greatest of ideas. And thus was the Magic Kingdom built. It thrived for many turns, growing larger and more distinct as new casters came to assist. Soon, it was a small continent, split into into eight distinct areas that the broad disciplines could mingle and study in, with the single original portal in the very center by which more entered. Then, disaster struck.
A great Ruler saw this this Magic Kingdom and and thought not of how easy it would be to find a caster to hire, but of the vast quantities he could capture and turn to his service - or croak to prevent others from doing the same. He struck with the full might of his forces, and even though the Predictamancers and Lookamancers gave warning, many were lost or sacrificed themselves in repelling the attack. At great cost, the Overlord was finally defeated, and the the Magic Kingdom decimated. But all were in agreement - this could not happen again.
Thus there was a grand assembly of casters, to decide what must be done. It was soon decided that the the Magic Kingdom must be forever barred to all but casters. Through their combined efforts, the entrance portal was twisted and changed, forbidding entrance to all but casters - the ultimatum being that to enter would be to face immediate disbanding. With this new perfect security in place, the chance to offer the construction of new portals in cities (for a price) arose. Soon the center of the continent was allocated for these new portals, and the area called Portal Park. Peace drifted back into place, and the Magic Kingdom was a haven again.
The casters never forgot the assault, however, and the threat of non-casters in their Kingdom.
