But what is an old man like you doing in this horrible mass grave created by a cruel king? I came here to mourn dear rat! Who have you lost? I lost all my friends... I am all alone All your friends are in this pile? Yes. Their bodies are among those If you would like I could find them and bring you mementos if they have any. I need to stay a little far back then.
