Vorlese is a an advanced, productive, and wealthy world that is typical of [[Segmentum Solar]]. It sits at the center of one of the eight major [[Warp]] routes to [[Terra]], making it a vital strategic world. After the [[13th Black Crusade]] and the formation of the [[Great Rift]], it was assaulted by the [[Black Legion]] in an attempt to shut down all the access routes to and from Terra. The Black Legion planned to drop a gigantic shard of a [[Cadian Pylon]] onto Vorlese, using its null energies to shut down Warp Travel in the area.{{Fn|1}}

In the subsequent [[Battle of Vorlese]], the [[PDF]] forces on the planet held out the best they could against the [[Chaos Space Marine]] assault while the orbiting Black Legion [[Grand Cruiser]] was boarded by [[Custodes]] and [[Sisters of Silence]]. They managed to prevent the Chaos forces from dropping the Pylon shard onto Vorlese long enough for [[Roboute Guilliman|Roboute Guilliman]]'s]] fleet to arrive, which subsequently defeated the Chaos fleet and liberated Vorlese.{{Fn|1}}

As a planet of importance in Terras Terra's warp routes, several of the main [[Navis Nobilite#The Navigator Houses|Navigator Houses]] has have Vorlese as their seat of power.{{Fn|3}}
