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.
