The Navis Nobilite hold the keys to the stars: it is only with their consent and complicity that any can venture from Port Wander into the Koronus Expanse. Without the Navigators’ third eye—their ability to see and navigate the tides and current of the warp—there could be no exploration of unknown regions such as the Koronus Expanse, and so it is that Port Wander (and all drawn to it) depends on the families of navigators for its continued existence. For their part, the Navigators are little concerned with controlling Port Wander, but the station is a battle ground for clan struggles: exploration into the Koronus Expanse offers priceless insight into the process of navigating uncharted space. As Port Wander is the gateway to the Expanse, many navigator houses see a dominant presence in the station as vital in securing contracts to explore the unknown. This knowledge improve the fortunes of a Navigator clan, especially if a route leads to a valuable world or is later designated for a crusade or colonisation. In such cases, the exclusive knowledge of a route and the skill of the clan navigators to steer it mean that they can command a fortune in bonds from the Imperial Navy or Merchant Cartels.
