To the best of my knowledge, and I am posting to help me get this correct, the time line of events is (roughtly):

- Prehistoric Abadin create the Labrynth and ascend to create the original 7 judges
- Ozmanthus Arelius, a pearless prodigy of the sacred arts rises to the highest levels on Cradle and develops Penance in the ancient labrynth before ascending to the heavens
- The dread wars are waged where 9 ancient monarchs attack the dread gods on Cradle thereby discovering that the dreadgods destruction is nigh impossible. Only 2 monarchs survive and the world is largely destroyed
- The 2 remaining monarchs establish the Uncrowned King Tournament to help raise up a new generation of monarchs, Reigan Shen wins the first Uncrowned King Tournament
- Ozmanthus Arelius, now known as The Reaper and 8th Judge of the Abidan, leaves the heavens and returns to Cradle under the identity of Eithan Arelius
- Tiberian Arelius is killed by Reigan Shen after a failed attempt at coorperation to destroy the dreadgods (as advised by Eithan Arelius). The Sage of 1000 eyes barely survives and Northstrider is thought dead for 12 years after the Monarch battle rises the Wheeping Dragon that devistates the Rosegold Continent
- Events of books start here

When was Emriss Silentborn orginally a monarch and then when was she assasinated?

when did Northstrider almost die from the Weeping dragon? Was it the battle with the Wheeping Dragon during Tiberian's death? I dont think it is because that battle was "8 years before the books" but Northstrider was thought to be dead for ~12 years, I think.

Anything else I missed? I think there probably is.
