Deepsight Orb

The Deepsight Orb is used in the Extraction Lost Sector, in Quagmire, to reveal hidden routes. After the sector's boss, a Deepsight cloud appears in the exit corridor. Interacting with it opens a passage into a room containing the larvae incubator needed for the Of Queens and Worms quest. Using the Deepsight also reveals a path near the Hive statue.

This is the final incubator stop in that quest.
