[If this was a Tolkien book this information would most likely be found in the Appendix B of 'The Lord of the Rings' part three 'The Return of the King'. Since I'm not Tolkien and this isn't about a character of his but of my own creation it is here that I will reveal such information so those who are familiar with the War of the Ring and the Chronology of the Westlands as in part three, Appendix B as mentioned.]
(If you have the third book please refer to Appendix B and read what happens in year 2951 and others years here marked with a *asterisk and consider what I have added as an addition. For those who do not own the book not to worry for I shall include what is shown in the book in years with an* as mentioned and also revel my additions that will lack the *!)
