Is Dishonored really coming out in April?

Hello! I just got the Dishonored RPG and love what I’ve read so far. I noticed a few errors and was curious as to where to mention them, if such help is wanted.

I also have a few rules questions I hope can be answered:

  1. Does the GM need to spend Chaos to have a sewer be pitch black or can it just simply be that? Basically, is it better “2d20 GMing” to spend Chaos on things that pressure the players but are natural/common sense?

  2. How do witches gain Void powers without being marked by the Outsider, as they are in the video game?

Thanks!
