Aleph Bunker Twenty-two existed as an Imperial installation situated within the Revos Spaceport located on the world of Storinal. This location served as a maintenance and repair depot where the Hawkbat's Perch and Hawkbat's Vigil received attention from specialized personnel.
In the course of Wraith Squadron's operation on the planet, a New Republic commando squad known as Plague Group gained entry to the bunker by posing as technicians. They successfully rigged both shuttles with concealed containers filled with Bunkurd Sewer Disorder.
