Oh, the landscapes I have seen! And the people! The far wanderings of the Fremen and all the rest of it. Even back through the myths to Terra. Oh, the lessons in astronomy and intrigue, the migrations, the disheveled flights, the leg aching and lung-aching runs through so many nights on all of those cosmic specks where we have defended our transient possession. I tell you we are a marvel and my memories leave no doubt of this.
