Sparborth IV is a Commonwealth planet that is notable for housing the "Shining Path to Truth and Knowledge Institute". The institute designs, creates, and overseas installations (as well as installing themselves) Artificial Intelligences in Commonwealth Vessels.
The name of the planet is most probably Vedran in origin, and the planet itself is not to be the only inhabited planet in its system.
The planet does not have its own High Guard unit, because the only inhabitants of the planet live in a small community that serves to house the workers of the Shining Path to Truth and Knowledge Institute. Given such a small population, and because every member is essential, the Commonwealth sends vessels from the High Guard to specially protect the planet.
