Dear penguin344, you are Eowyn of Rohan.
You are the Lady of Rohan, niece of King Theoden. You disguised yourself as a man so as to be able to fight and win glory in battle.
You are strong enough to take on even the Witch-King of Angmar, and as such any mere kill attempt on your life will fail. Of course, it will sufficiently weaken you that a second strike would probably do you in.
You also count as a Rohirrim yourself for all voting or ability purposes, and as such know that if all living Rohirrim vote for the same person you may vote during the day and, if all living Rohirrim vote for the same person during the day and that person is not lynched, your band will ride that person down and impale him or her with a spear at the end of the next night, thus killing him or her. However, your band has a limited supply of spears, and so this will only work once every two days.
Having faced him in battle, you can feel the presence of the Witch-King of Angmar in this fight. You also know that, as a woman, your vote will pierce any protection in place on him.
You are allied with Middle Earth. You win if all threats are eliminated.
