Presumably varied (as per tectonic activity)
Old Faithful is a tectonically active planet located in or near the Koprulu Sector. One of the most dangerous planets ever found by the Confederacy, a tectonic anomaly strikes every eight minutes, all individuals on low ground guaranteed to be incapacitated when this occurs. However, structures can survive the tremors.
Despite the activity, or perhaps because of it, Old Faithful is one of the richest planets in the Koprulu Sector in minerals. To harvest these minerals, the Confederate Mining Consortium awarded mining rights to four firms. However, Mr. Slate, a high ranking official in one of these firms, instructed a lower officer to ensure that their company would be the only one left to begin mining. As such, the firm engaged another over the mining rights, bearing with the tectonic danger.
