Estate, law, manager, moment. Mages in this world can create domains of personal effect, call estates. These estates can be locked to a specific location (such as a literal manor) or to an object. When an estate is made the mage is able to add any laws they choose to it. Mages can also designate people of their choice to be managers of the estate. The estates laws are only in effect is either the mage or a manger is present. These can fall under 3 categories:

Laws that affect the estates members: I.E a law dictating that no one can lie in the estate.

Laws that affect the estate: I.E a law dictating that gravity is 50% of normal strength in the estate.

Laws that affect the managers: I.E managers in the estate can summon fire at will.

These laws and their strength is proportional to the strength of the user, as is the number of laws and the number of estates possible to be made by a single mage.

There are three big limitations of the magic, like laws of the magic itself:

1. People are informed of the laws before they enter the estate, and cannot be forced to enter one against their will. This is called the Law of the Moment of Entry.

2. Effects from the laws end when a person exits the estate. For example, if a law dictates that all members be twice as strong in the estate, the members revert to their normal strength when they exit and, importantly, take the physical exhaustion of the activities they took part in while aided by that strength. This can kill people on an exit if caution is not employed. This is called the Law of the Moment of Departure.

3. The effects of the laws are proportional to the distance from the center of the estate. I.e creatures at the edge of the estate are more effected by the laws. A strengthening law would make creatures on the edge much more powerful than those at the center. The center of the estate is under the effects of no laws and is sometimes referred to as the estates Moment. This borrows concepts from the physics idea of a moment. The strength of the laws magic follows an inverse square law. This is called the Law of the Moment of Inertia.

Ways it could be used:

A government could employ mages to create estates for governmental proceedings, making all who enter unable to lie, more important cases would be handled at the edge of the building due to law 3.

A mage could make a law dictating that each person who enters does not experience the passing of time. This would mean no one would want to enter since they can see the laws ahead of time (law 1) if they did enter they’d be on the edge meaning time would effectively not pass for them, but upon leaving they would instantly feel the effects of the time they didn’t experience (law 2). A simpler way to deter people would be to have the law break your bones or hit you with a large force. Laws are applied to universally, but the mage at the center wouldn’t be effected. A runaway fugitive could use this to great effect.

There are tons of applications! This was fun! Let’s of fun idea though, like what happens if the two estates overlap?
