Short paragraph explaining what happened on another thread.
I am following the main story line as a marauder/gladiator and the last quest I finished was Power of Deduction I completed that and now there is no quest marker anywhere. According to my friends the next quest is "Wrath of Titan" and they cant remember where you start it. Any help will be great.

I'm stuck in the exact same place. Have you found a solution or submitted a ticket?

Yeah, they are taking their time responding to me.
