Dimensional magic

Dimensional magic is a type of magic which is centered around bending space. The most notable example of this is William Norland's house. Through the use of advance dimensional magic by an unknown wizard, a door in the Wizard Norland's house was enchanted to lead to a numerous variety of locations.

Another, smaller, example of dimensional magic is Howl's door that was a portal to four different locations, each location corresponding to a particular color on the knob.
