You are
Little Gumball,
mafia-aligned lazy actress.
Act out a death scene: Once per game, you may choose to fake your own death during the night. You will show to have been a night kill the following day. You may reveal that you are alive at any point by posting in the thread. After a day of pretending to be dead, if you haven’t already revealed that you’re alive, you will be revealed to still be alive. (Abilities may still be used on you when you’re playing dead, but you will not show up in the player list or vote counts as alive).
UwU voice: You appear as innocent to investigative checks that would show either your alignment or whether or not you are capable of killing other players.
Insomniac: You may post at night.
Your servant is
Caster (William Shakespeare)
You summoned Shakespeare using a copy of a Midsummer Night's Dream script you had lying around as a catalyst.
First Folio: You may write the death scenes of kills you perform.
Enchant: Once per day you may quote another player’s post in which they vote for another player and write a bolded poem about how they are right. The vote you enhance will be worth an additional vote. This ability will only work during the first 3 days.
