Minor rewording for clarification in introduction.
16 March 2020
Fix erroneous statement about the Second Age; in fact this
should have read 'Third Age' but in my tired head this did not
register enough. I have not documented the story of the Witch-king
taking Fornost (1974 of the TA) but that is where it was said he
dwelt when he was assaulted (as above). At the ending of 'the evil
realm Angmar' the Witch-king escaped 'from the North and came to
Mordor, and there gathered the remaining Ringwraiths, of whom he was
the chief. But it was not until 2000 that they issued from Mordor by
the Pass of Cirith Ungol and laid siege to Minas Ithil. This they
took in 2002, and captured the palantír of the tower.'
Also add the year and date of the end of the Ring (since it was
mere days after the fall of the Witch-king).
