Someone

If you see 'someone' gossiping, shouting, or doing something, it means it is a Player Character who you are unable to see. If you have the true sight spell up, or a true sight item on, that 'someone' is a god. If not, it may be a god, or it may be someone invisible, someone in a dark room, or it may be you that is blind or in a dark room.
