The industrial site called Wind Pass is not exactly located at the pass itself - the rocky spires that cut it into separate corridors there look uninhabited. Instead, it faces pole-ward on the slim peninsula that constitutes the eastern arm of the pass. The peninsula itself is dotted with windtrap installations facing both sides, collecting powerful winds from the desert and moist air from the pole.

The base itself is rather peculiar: the basin between a crown of rocky heights is the landing field, whereas all industrial installations descend into the caverns around and below, through a fan of entrances, each barred by a solid plasteel door. The extent of the whole complex is thus not known to any outsiders; its depths may hosts facilities of any kind to which passages are well-hidden. For anyone who has ever been in the great caverns of Ix, the semblance of design would be striking, as would be the extent to which the whole structure is governed by technology. It would fill anyone living by the precepts of Butlerian Jihad with unease, though it is hard to say whether anything here actually crosses the boundary.

Harkonnen security is high here; a lot of defences are automated and cover both air and ground domains. It is essentially a mountain fortress, with an inner courtyard where up to medium vessels can land.
