Outskirts

At the edge of the city are the Outskirts. The wall itself is the biggest feature of the Outskirts (literally), standing at 150m or 492 feet tall at its standard points and 200m or 656 feet tall at its towers. The wall is constructed of fairly standard materials that are enough to keep out your average human, but there are a few specialized components to keep it from damage by Spawn or otherwise Augmented or Jinxed humans. The most notable of these are what are colloquially known as 'Light Walls' - a visible layer that disrupts Augments and Jinxed powers, as well as the 'Frequency Gates'. Frequency Gates are specially tuned both to nullify a Spawn's use of sound to damage and echo locate, as well as emit infra-sound to deter them from approach or entry. A few frequency ranges are known to actively hurt Spawn, though their use has fallen out of favor after the wars.

The towers take two positions - while both are connected to the main encircling structure, the Ivory Tower is surrounded by a Frequency Gate and Light Wall, whereas both Gate and Wall pass behind the Obsidian Tower between that section of wall and the main city. The Ivory Tower is home to ambassadors and travelers and contains a customs department, as well as a direct SubGround tunnel between it and Zenith. The Obsidian Tower is home to Spawn ambassadors and contains facilities to suit their needs, as well as meeting rooms on-site for Human-Spawn relations. While humans can visit, very few see the need or have the desire to do so.

On either side of the wall, a small collection of ramshackle buildings and tents make up the 'living space' of the Outskirts. While there are a few permanent fixtures and resources (notably, several bars), the Outskirts are more a place to pass through rather than make a permanent home, although many career Hunters and Ravengers maintain something of a residence in their major cities of choice. Many of the former old world structures have crumbled or collapsed to leave metal beams and wire paths exposed, making it prime territory for Skimboarders.
