Hidden One, when I say "spoke quietly so as not to be heard" it means you don't hear it. We're all vampires so we know how loud/soft we need to be to be heard or not to be heard. Please edit your post!
Vekarin sounds a lot like him, however, I think Vekarin's voice would be a bit deeper and a lot louder. He's a massive guy with a 'booming' voice, and the son of Abhorash too, but, apart from the factors of volume and pitch, yeah, Vekarin sounds pretty much like Shao Khan.
Edit: should post the supplemental tomorrow, though cannot be 100% sure due to time constraints. Life is getting really busy for me these days...
I have posted a Supplement, which describes in more detail what Shah is thinking about in my latest post in Chapter 5 - it's a flashback. I have also edited my latest Chapter 5 post to make the flashback actually fit in better, and to expand it; it was a bit bare bones and basic, but I just wanted to post - hopefully it's better now.
