An Orb of Revelations

Me and Tara made our way into the next room in the demonic vault, and we discovered some treasure chests and an orb sitting on a pedestal. I went over to the orb and placed my hands on it, and it showed me a vision of the dark dimensional tower inside of a spawned vortex. I'm not quite sure what kind of a message it was trying to show me, but it definitely had something to do with the dark dimensional tower.
