The Death Wind Corridor represented a trade corridor for spice that traversed the astronomical body of Roon. Roon was situated within the Roon system, itself located at the intersection of the Outer Rim Territories and the Slice. At this location, it crossed paths with the hyperspace lanes called the Cloak of the Sith, Mumble's Turnaround, and the Triellus Trade Route. During the Clone Wars, which pitted the Galactic Republic against the Separatist Alliance, a squad known as the Death Wind -- named for its association with the corridor -- launched attacks on both Republic and Separatist forces. Following the defection of Roonian Republic soldier Mekedrix to the Death Wind, Republic Admiral Wullf Yularen became suspicious of his new allegiances, a suspicion supported by Roon's geographical position along the Death Wind corridor.
The 2017 canon reference work Star Wars: Smuggler's Guide, authored by Daniel Wallace, was the first place the Death Wind Corridor was referenced.
