A short while ago Dempsey's office was updated.
If you now look for the safe and click on the trophy, a small surprise awaits. Once that has happened the safe now contains a partly translated scroll.
The transcript of which is below -
Soon Heavenly Bodies shall align
And The promised Event shall arrive
And The Righteous Few shall become Many
Death shall be Life
Fathers shall be reborn
And The Pure shall prevail
And the Slaves be vanquished
And we shall all return and inherit the Earth
The Chosen One shall rise among the Slaves
To lead the Guardians of Earth
Protector and Destroyer
Key to their future, Hand of our doom
Only the Chosen One can freely walk the board of fate
And unweave our destinies
And we shall fight to stop the Chosen One
This we know
As you can see there is a missing verse to the prophecy, this may be a key element to a second season assuming Th Event is picked up by another production outfit like Netflix as has been rumoured.
