Мафия 35. The Heads

You can, of course, connect void and "another world," but I find it less convincing.

But here you are wrong, because we are talking about League of Legends (at least, they were the avatar and signature for a long time), and there the Void is indeed another world.
The clues are strange; I haven't come up with anything concrete yet. For now, it's NNV.
