Please, take this with a grain salt like usual since its mainly only theories and we can’t be sure for now due the story not being there yet.

As far as we can tell there are 2 different dawns referenced in the lore. One is revolution and the other being new tomorrow.

One is easy to know that being new tomorrow which is also known as the dawn of the new era. Which is basically the next era after the revolution. We think at least, we really aren’t sure where the new era is but we know it is referenced and we have yet to place it.

The second one is a little more complex, that being the revolution. The main one we are aware of is the usurpation of the empire from within and the rebelling of charons in the empire.

We also do believe theres another possible revolution taking place during the story. That being against the deities in the church.
