The magic laws govern magical interactions.

The first 2 laws relate to magic in general.

1) All beings have to potential to use magic.
2) Magic, like energy, takes different forms. But, unlike energy, is created when someone learns to use it, in the form of Mana.

The next two laws relate to how abilities work.

3) When an individual has at least 80% of a casters magical power, certain talents will not have an effect on them.
4) Higher magical power spells deal increased damage compared to lower magical power spells.

The next 3 laws relate to dimensional travel.

5) Mana is stored over multiversal travel, but changes how it works, based on the other universe's laws.
6) Entities categorized as type=null do not maintain Mana between dimensions, or even form. Partially type=null entities, however, suffer impairments, but can still travel.
7) Mana cannot travel between universes without a host. Thus, Mana used in one universe will not recover when in another universe.

The last 2 laws relate to the Lost Realm.

8) Mana will ignore law 7, when the Lost Realm is the receiving universe.
9) The Lost Realm ignores law 6.

Another short one, but this is another standalone topic. Sorry...
