The Beholder is on the Villager team.
During the night phase, the Beholder will be instructed to open their eyes. They will be given the opportunity to see which players are the Seer and/or Fortune Teller. They will also get to see which player is the Apprentice as long as the Seer or Fortune Teller is also in play.
Because you know who the Seer and/or Fortune Teller are, you are in the fortunate position to know whose questions to trust, as both of those roles posses information about the Magic Word.
