Will there be a sequel?

The problem isn't really that big; he survived, and the fourth game mentions Tarnum, but what happened before that? Maybe he repented and wanted to resurrect his sister, so he joined the Necropolis. Or maybe he turned to the K'tharr for that purpose, or even to angels! There are tons of possibilities; let's suggest more and choose together, and then we can start making sketches. Otherwise, we might create something about the Necropolis and end up working on Inferno or Castle instead. We need to decide everything first and then start sketching out what this continuation will be. What could have happened between the fourth game and *Armageddon's Blade*? What are your thoughts? Maybe he started helping the Barbarians regain their former strength.
