Mafia 92. Void Lord.

I think the clue isn't related to Heroes of Might and Magic. Because it's in everyone's profile, but the clue should be something unique, I think.

The problem is that half of the people have Heroes of Might and Magic in their profile, and many of them don't have anything else at all.
For now, I only see a direct connection with Heroes of Might and Magic, but I agree that we need to look for something else.
