You may choose your alignment from Town or any scumteam existing in the game. This must be done pregame, otherwise you will default to Town.
If your role is rolled, every player gets a Self Role Reroller invention, allowing them to reroll their role but not alignment.
If you are Town-aligned, you have a 1-shot ability to add someone to your private topic, which you may give any name you wish. You will also know if they are Town-aligned or not.
If you are groupscum-aligned, you have a 1-shot ability to perform the factional kill as if it were Strong-Willed, and you may write your own flavor for the factional kill.
If you are third party-aligned, you may reroll your role but not alignment, and a target player's role but not alignment.
