This song, like the following two parts is about a personified Death. Here we have Death himself visiting a "victim". He laments that he has no say in where he is sent, he simply follows orders and goes. The main thing to take away from his words are the inevitability and finality of his presence because they come into play during the next two parts. He may be bound in his activity but he fully understands the power that follows him. Which is why he tells those he visits to "settle in". They have no way of avoiding what is to come so he tries to ease their transition.
