- "And to do that, we must go to the lower levels. The underworld."
- ―Plo Koon
A portal led into the heart of the Coruscant underworld during the time of the Galactic Republic. A massive ventilation shaft and shipping portal, it allowed for starships to enter and exit the extensive undercity of Coruscant.
Besides serving as a shipping portal with access into the Coruscant underworld, the ventilation shaft collected numerous sewage shafts from nearby buildings on the surface. One of those pipeline networks originated at the Republic military base.
