Bunker Twenty-two Aleph was an Imperial base inside the Revos Spaceport on the planet Storinal. It was where the Hawkbat's Perch and Hawkbat's Vigil were serviced by technicians. During Wraith Squadron's mission to the planet, Plague Group infiltrated the bunker disguised as mechanics; managing to booby trap both shuttles with vials of Bunkurd Sewer Disorder.
