The Verifex Nebula as seen from Adhara Treaty region
Formerly the Open Cluster M50 in Monoceros, 3200 ly from Sol, This nebula was formed when 154 artificial Supernovae were detonated almost simultaneously in 7981 AT.
This event, sometimes called the Gehenna Incident, caused severe ecological damage on many worlds in a region one thousand light years across, mostly in the Orion Federation. The resulting nebula, named after the rogue archailect responsible, Verifex, has been expanding rapidly ever since.
