Btw, will there be any children in DD2? It'd be very interesting if ,say, there were children who were like Black Ring protege members and the protagonist is confronted with the dilemma on what to do without killing them. Protege members as in: perhaps they're the children of various Black Ring members, or they're even from orphanages set up by the Black Ring.
After all, think about this? What would be better than children who're fully entrenched in your beliefs and who worship the Damned One? By the time they're in their teens, they've fully accepted the teachings and are glad to fall in love with one another and continue a wonderful legacy. (Incidentally, I remember a very short scene in a very old movie where there was this child, clad fully in costumed glory, and praising the cult!)
For example: he could have them placed in a house, that's guarded by paladins or very smart warriors. But at the same time, he'd need to take precautions so they don't go on a killing spree. After all, they might be children but they're also wielding some form of powerful magic that could kill many.
Edit:
Also another thing: it'd be interesting to be able to infiltrate the Black Ring. Pose as an interested Black Ring fan and approach one of the guards and find out as much information as you can.
And another one: to be able to win over various Black Ring members over to your side. I mean, they might have been forced to join or even owed some form of allegiance to various members.
And also: it'd be interesting to have various backgrounds for the members of the Black Ring. Why did they join?
Perhaps for some of them, they might've suffered constant abuse at the hands of various family members or even other individuals and developed an addiction towards it(psychological issues, basically). And this addiction overcame their feelings of empathy, etc. Therefore, you could release them from their addiction and if they're thankful, you might've gained a few formidable allies.
Edit: Yet another one. How about certain Black Ring members having certain amount of fame like a superstar? That means there'd be people who'd do anything for him/her.
