Talk:Operation: Buried Debts/@comment-50.30.149.47-20190310084624

This whole event likely refers to Fortuna's past in the time of Vox Solaris. The hidden locked door seems to be the entrance to the old vox solaris base which may have also been linked to the factory/mine/whatnot that came before Fortuna. You can see the surface entrance in a poor state just beyond the map next to the cave.

The debt that cannot be repaid is most likely referring to what vox solaris accomplished for the people of Fortuna, or a locked away and forgetten debt relating to Nef Anyo.
