Carradice: 1) Wondering if it might be possible to get a recap on the special characters besides town and mafia (unless they are to be a surprise).
The most common ones would be:
_Cop: investigate a player at Night to learn if they are Town or Mafia.
_Doc: protect a player at Night. That player won't be killed.
_Tracker: investigate a player at Night. You learn if that player targeted anyone during same Night.
_Watcher: investigate a player at Night. You learn who else that player was targeted by during same Night.
_Vigilante: Town player who can kill at Night. Usually limited (e.g. 2-shot - can only do it twice).
_Roleblocker: target a player at Night. The target won't be able to perform any actions that Night.
_Strongman: Mafia killer who can bypass Doctor protection. Usually limited (e.g. 1-shot can only do it once).
_Godfather: Mafia player who registers as Town to a Cop investigation.

Did I miss anything?
And many more. Some are quite exotic and rarely seen.
Sometimes mods create their own roles, or modify existing ones.
You can find a nice list here:

Carradice: 2) Will you assign everyone a RP (flavor) role or it is up to us to pick one?
I will assign you your faction, any special character role (if any), as well as a name from the Harry Potter universe and some flavour. It's up to you how much you want to roleplay that.
EDIT: Yes, Lifthrasil got it right, regarding closed setup. Meaning no one will know in advance which special roles will be in play.
EDIT 2:
And let's not forget Siblings. Two town players who if one is killed the other dies too. I Love that special role but it's never seen in practice.
