Aspera is a small, mostly uninhabitable world that served as a vital location for the Sovereign Colonies' Red Marker experiments.[1] Aspera was possibly located in the Gliese 581 System.[2]


Aspera was initially selected as the location for a penal colony for political prisoners. This was due to its extremely remote location and low level of natural resources, meaning there would be little, if any, interest in exploring the world.[1]

In the 2290s, eighty years after the Black Marker was exhumed from the Earth, Aspera was chosen as the site of one of three new military installations to be used to investigate and recreate the Black Marker. The research facility was set up near the penal colony, so the prisoners could be used as test subjects, if need be.

Not more than a decade after the installation was created, Istvan Sato was transferred there after killing politician Tim Fischer on Vindauga. Not too long afterwards, the site's Red Marker, Marker 2A, activated, and the destruction of the penal colony and the research station was imminent. The penal colony was overrun by Necromorphs, with only Henry Wandrei surviving by locking himself in a control room. He was eventually "rescued" by Jensi Sato, Istvan's brother. They made their way to the research station, which, while infested with Necromorphs as well, also had a number of scientists and researchers who were still alive. There, Jensi and Henry, along with Dr. Callie Dexter, confronted the Marker.

It is unclear if there were any planetside survivors. Before leaving, a SCAF gunship captained by Commander Grottor began to deploy several mines in orbit around the planet.[1] Aspera was ultimately blacklisted during the execution of Scenario Five in order to leave no evidence of experiments on Markers.[3]
