Gate

A Gate was an instantaneous passage between two points in spacetime. Gates were created and managed by gatemages. Many types of gates could be made including public gates, closed gates, viewports, and Great Gates.

Great Gate
A Great Gate was a passage between worlds created by a powerful gatemage. Great Gates consisted of a dozen or more normal gates intertwined and thrust outward into spacetime to connect Westil and Mittlegard. After passing through a Great Gate, a mage's power was greatly magnified.
