The Seer is on the Villager team.
During the night phase, the Seer will be instructed to open their eyes. They will be given the opportunity to see the Magic Word.
If the Villager team correctly guesses the Magic Word, the Werewolves will get a chance to guess who the Seer is. If they are correct, the Villager team loses.
The Seer knows the Magic Word and wants to help the Villagers guess it. However, if they make themselves too obvious, the Werewolves will cotton on to who they are and the game will be over. Try and ask questions that are able to prompt other people into asking the right questions. If you can tell somebody is repeatedly asking misleading questions, they may just be the Werewolf!
