I wish there could be a way to trace our prophecies same as any quest.
Circle of Fortune already shows you where to find the prophecy objective and what the reward is, and you can view all active ones in the prophecy panel.
That said, a nice improvement could be showing small icons on the map near monoliths or dungeons that have active prophecies tied to them—would make it easier to spot them at a glance without porting back over to the Observatory.
I suspect the OP knows that & is asking for a way to see what prophecies they have already taken require which timelines rather than hovering over & reading through each & everyone individually…
You don’t need to port back to the Observatory to see what prophecies you have, you can see it from the CoF Prophecy tab.
