Note to any future victims of terrifying beasts: it's nice that you have the presence of mind to write about your last few minutes on this earth, but it would be helpful for those coming after you if you would take a few moments to describe the terrors you are facing. What kind of beast is it? What makes it so dangerous? If you had to face it again, what weapons would you bring? Where do you think it will go next? Is there any way to defeat it? Referring to it as "it" and "he" and taking up most of your diary entry explaining how you feel is not very useful.
