This unidentified planet is a rocky wasteland on which Midnight's Cairn, Maliwan's secret facility, is located and is featured during the Takedown at the Maliwan Blacksite.


  • The view of Midnight's Cairn seen from the bridge of Sanctuary III appears to be reusing the model of Promethea, but with the perspective moved to show the planet's night side.
  • The Ratch on the planet were most likely brought there unintentionally by Maliwan themselves. It is unknown if the planet has any native fauna.
