The lines in the cinematics about being the “jailor of the damned” “that power will be your prison” .
The Jailor of Torghast, tower of the damned. Seems like Blizz’s cheesy writing smacked dab in front of us.
We defeat the Jailor in the final patch and then Tirion places the Jailor’s crown on Bolvar head and yadda yadda...
Don’t put it past Blizz, they would absolutely do something like this and call it a new and exciting plot twist!
