Saurian Augury

AKA the Dragon Prophecies or Draconic Prophecy, these are not discussed by most outside of the eldest dragons or elite scholars.
By those who know of these things they are considered either gospel or a hoax.
They are very much explored by the Astronomia Praesidium Societatis, which is why they explore space and the planes to such extent as they are aware the dragons will awake leading to the destruction of all.
They are also aware that all other places in the Phlogiston don't exist and that the Far Realms is beginning to crack the edges of the Astral Shell.
