You were told about this place by Qarbo in Sacred Stone Monastery. He told you that the stairs in the Monastery would lead to the Temple of Black Earth. Then you killed him.
Ascendant campaigns can view previous versions of their pages, see what has changed (and who did it), and even restore old versions. It's like having a rewind button for your campaign.
We've already been saving your edits, so if you
you will have instant access to your previous versions. Plus, you get a 15-day free trial, so there's nothing to lose.
