In
Mage: the Ascension, the study of the
Sphere of
Correspondence is the study of relationships between patterns and how to exploit them. The prevailing theory (coincidentally toted by more traditional
mages) is that because all things were once part of the
One, they still remember their common bonds.
Correspondence effects are easier to work when there is a physical, mental, or spiritual link between the two objects- a
mage will be able to teleport into her childhood home easier than it would be to teleport into a bathroom in the
White House.
An apprentice in
Correspondence is able to spot inconsistencies in the
Tapestry such as spatial instabilities and wormholes and produce small objects out of thin air, while greater competancy allows a mage to bring other people with her when she teleports between places, and the capacity to truly
be in three places at once.
This
Sphere is the home seat of the
Virtual Adepts, and before them, the
Ahl-i-Batin.
