Waygate

A Waygate is a network of ancient magical devices scattered throughout the world, usually found in major cities. One was located in the basement of the Tower of the Arcanites. They were constructed by mages over a millenia before the Resarian Imperium. The knowledge of how to construct these gates was lost during the brutal conquest of Emperor Rantiva.

The Waygate device is two pillars with an energy field between.

The Waygates only worked for mages or a mage and a non mage in physical contact with the mage. In that instance, only the mage could control where the travelers were going. A mage simply thought of his destination and passed through. If that destination had a Waygate, he'd arrive there instantaneously. If not, then the traveler merely finds himself on the far side of the same Waygate.

Waygates were made defunct in the War of the Necromancer. Raeldrek and Sarastae did modification to the Waygates, allowing their armies to pass through without mage escorts. They used the Waygates to take over the Tower of the Arcanites and take Darincedon from the inside. As a response, recognizing the threat, Scholar Gromrak, an Orc from Grom'char, returned to his homeland and with a number of shaman, he overloaded the Waygate with magic and obliterated it, shutting down the entire network.

They've never been fixed since.
