Consortium Arches

Apparently rediscovered by people in 497, these ancient stone 
portals allow travel across distances from one arch to another, across 
not only Xaria but, likley, other lands..
These are great stone arches, spanning some ten feet with and twelve 
feet high, embedded with runes and built in long ago, possibly at the 
beginning of the 2nd Age of the Consortium.
Who built the Arches and how someone can enable them to work is not know to most Xarians.
