So I found this on the forums, the re-telling of “The Akallabeth” talks of the transition from 1st age to 2nd and the start of the 2nd age.  It is from the Silmarillion which I still haven’t read – and don’t get too excited Merric, I have read the LOTR books and Hobbit (the actual books) numerous times.  Check it on on the forums – Akallabeth.
