Stone Ring

The Stone Rings (also known as Intergalactic Gateways) are large, ring-like structures created by the Titans in the early First Age to help mortals travel to different galaxies without having to spend millions of years in the Intergalactic Void.

Overview
The technology behind the Stone Ring is still not understandable today nor is it feasible with any mortal technology today. They function as artificial wormholes linking two locations in the universe. A twin set of rings will allow for two-way travel, but if one of the rings is destroyed, travel will only become one-way.

Locations
Very few Stone Rings have been discovered throughout the universe. Most local laws forbid travel through them because no one is sure what sort of threats might arrive.

Milky Way-Tenebris Gateway
The Dhragolon used this gateway to get to the Tenebris galaxy. They would soon invade Azur Kodothh Ren. After the invasion, the Dhragolon deactivated the gateway from both sides so that any potential allies of the Krodreths Az could not enter it. The Dhragolon would have destroyed it, but they were unable which would allow the Universal Council of Justice to reactivate it many years later.

Dhragolon colonies in the Tenebris galaxy exist but they are completely cut off from the rest of the Dhragolon Federal Monarchy.

GHD galaxy-Milky Way Gateway
A renegade group from the Great Horned Dragon Empire arrived in the Milky Way galaxy during the first year of the Fourth Age and would join the Galactic Senate. The Milky Way side of the ring was destroyed during a war between the Omni and the Harbingers making this gateway a one-way trip.
