Jörmungandr

Floating in orbit high above the Planet Underhill, the many segments of the Jörmungandr stand guard over the planet below, watching for those who might attack, and those who might try to escape

Purpose / Function
Originally anchored around the colony ships that orbited the planet, the ring monitors Underhill and guards against incoming threat. Since the planets of the solar system have been at peace with each other for the past few hundred years, it mainly guards the surface of the planet, maintaining a link with the keyposts below and projecting a scaled down model of the terrain into the central spaces of each segment of the ring, making it possible for the monitors to track changes and possible fluctuations in the ley-lines.

Alterations
The ring wasn't a ring at first. The ships that the colonists arrived it were left in orbit in several places around the planet's equator, facilitating satellite uplinks and communications between the colonies. Once the people realized that settling the planet would be harder than anticipated, some moved back up to the ships to make use of the genetic manipulation facilities that had been left on board in the assumption that they were no longer needed. After the Gene Wars were over and the dissenting factions thrown out of the system, the remaining colonists took the four ships left and used them to create anchor points for the shield ring. Now, thousands of years later, it is made up of the husks of the colony ships, a number of medium sized colony platforms, and a multitude of smaller satellite arrays. They form a ring around the planet's equator, linked by navigation and communications, and allow those who can't survive on the surface, as corrupted by the tech-mage bombs as they are, to monitor and safeguard those below.

Architecture
The hulls of the original colony ships can be seen, here and there, among the welter of additional modules added through the years. The newer platforms that make the majority of the midsized modules are diamonds, curved to mirror the planet below.

Docking Slings
For those with less magic, and for those with less control of their porting abilities, drakes, dragons, and various other ships are used. Docking Slings are used to anchor them to the stations when waiting for passengers
