Arkos

The Arkos (or simply “Arkos”) is the world-ship and the primary location for the events in The Arclight Saga. Designed and built by the Old High Gods (with the aid of the dragonkin and the First Ones) it is a massive superstructure that hosts continental landmasses, oceans, and thousands of species. The inhabitants of the Arkos are unaware that the planet is, in fact, a space-faring vessel.

From a great distance it appears as a spherical disc with six equidistant pylons and a protruding bottom. The sun and moons are artificial satellites simulating night and day. The Arkos is composed mostly of aventium and is thought to be thousands of years old. The Old High Gods apparently abandoned it and all the inhabitants many hundreds of years ago. The reason for this is unknown, and many of the systems left behind have begun to malfunction.

The Arkos runs on templuric energy, such as that given off by the Arclight of the Magisterium. This creation energy adheres to biological entities and is shaped by the thoughts and emotions of those it binds to.
