My question is as follows: Is there only one Black Hand at any given time within Tamriel, or does each chapter of the Dark Brotherhood (ie, Cyrodil Chapter, Skyrim Chapter, Morrowind Chapter) have their own Black Hand?
The reason I ask is because it seems unreasonable for 5 people to have to coordinate Chapters of assassins across Tamriel, it seems to me like each chapter would have it's own Black Hand, with a Speaker in charge of every Brotherhood sanctuary, reporting to that chapter's Listener.
Also, on a related note, how many members are in the Black Hand. Obviously there is the Listener and the four Speakers, with a Silencer for each Speaker. However, the thing that I'm unclear on is if the Listener him/herself has their own personal silencer.
Thanks for any help!
