The fourth planet in the Rihlah System, called Shorvu (“sure-vu”) was terraformed by the Xi'An Empire as a barracks world, dotted with facilities to train and house military ground forces as well as mid-range weapons factories capable of equipping them. With the drawdown of the last century, the military factories of Shorvu have been methodically dismantled and replaced with corporate industrial zones (the very sight of which is a fascinating process, as massive Xi'An-driven mechanical ants strip structures and other objects back into their component materials).
Today, the conversion into an industrial world is nearly complete, although there remain scars of the former military occupation everywhere. Xi'An corporations have moved to Shorvu in force. Unlike most (In fact, close to all) Xi'An worlds, Humans are encouraged to visit Shorvu, via a landout in the industrial complex at Yahti, a former troop-training megapolis. This was a calculated decision on the part of the Xi'An governance: corporations needing to interact with Humans are given tax breaks to establish offices in Yahti, keeping Human intrusion into Xi'An space to an absolute minimum. The result is a corporate “office park” with outlets occupied by the big players, from shipbuilders like MISC–Xi'An and Aopoa all the way to food processing companies and simple import/export barristers.
The culture is an interesting mash; many of these outlets hire mostly Human staff, but insist on traditional Xi'An customs and methods of interaction. The industrial regions surrounding Yahti are also largely Human-centric. Any Khartu-al purchased will travel through a line near Yahti, and several MISC-overseen factories pump out Xi'An-acclimatized models of the Hull D. Shorvu also buys outside goods to fuel their industrial development. Heavy metals as well as a variety of electronics are in demand here, and the population has become acclimatized to purchasing these from Human transports where necessary.
