Fo everyone to see, here is my role pm:

Spoiler Alert, click show to read: 
“Treat your friend as if he might become an enemy.”
- Publilius Syrus

Tiberius Claudius Nero (Tiberius Nero)
Senator
(Optimates Faction)

The gens Claudius are nearly as old as the Republic itself, and you are a prime example of their aristocratic heritage. Your father was an ally of Gnaeus Pompeius Magnus and took a strong stand against Lucius Sergius Catilina’s failed Populares uprising. Everything you have been taught, and everything that you are, is a conservative and an Optimates in the finest traditions of Old Rome. Yet, you have always admired Gaius Julius Caesar. The man is charismatic and friendly to those who would be his friends, including you. More than once has he extended a kind word when it was unnecessary, or voiced support for you in the Senate when it was of no benefit to him. You know that there would be worse things in the world than Caesar as Dictator.

Should you wish it, you could cross over to the Populares at any time; Caesar’s blessing would surely be enough to convince all of his followers to accept you. Then again, you could also aid the dying Republic. There are few in Rome who possess your unique political flexibility, and it will allow you the freedom to chart your own course, going wherever the winds of fortune take you.

Victory Conditions:
(1) Eliminate all Caesarians and Pompeians. You will be victorious even if you are dead if this goal is met.

OR

(2) Survive and eliminate all Populares Faction Members, including Caesarians.

Role Description:
Night Actions:
(1) With 1 other Senator, you can investigate one player per night. Successful investigations will show the target's faction.
(2) With 2 other Senators, you can attempt to protect one player per night. Any player you protect will be very difficult to kill that night.
(3) With 3 other Senators, you can attempt to kill one player per night.

Special Ability:
(1) Damnatio Memoriae: Despite your long-standing ties to the Optimates, there has always been a part of you that has sympathized with the ideals of the Populares. Unlike most Senators, you are capable of crossing over to the other side and convincing them that the shift was sincere. Of course, such an action would only be believable once. You can switch your allegiance to the Populares at any time, but you cannot switch back. This will permanently change your role and victory conditions to those of a Populares Senator.
