Wonderland

Okay, lovely choice Alice. You stare out the Gothic arched windows, wondering what lays beyond the endless sea of trees. You ponder this until you here a knocking at the door. A light tap that you immediately recognise as your butler's knock. "Come in" You say loudly. Your butler walks in and you turn to look at him. "Lady Alice, a letter arrived for you this morning." He informs you. You look down at the letter. You don't recognise the seal. What do you do?
