Hark'azai Curtain

From Halo: Daybreak

The Hark'azai Curtain is a diffuse supernova remnant located within the fringes of the Siakar Expanse, and is part of the wider Kelsac Periphery. The Hark'azai Curtain was one of the Covenant's fleet attack routes during the Human-Covenant War, alongside the Jjaibii Shroud. Considered a backwater by Covenant standards, it is an unstable region home to many small pirate bands and factions of variable repute. Despite this, access to the Pleiades Corridor provided by the nearby Ouras Transit Node, as well as the secondary trade routes running to the Hezzaggor Verge make it moderately active in the post-war years.
