[Anguirel]

I feel that an almost more interesting question would be: how did Elessar's Empire decline and decay?

As it stands at the end of the book, Elessar is pretty uncontested, especially thanks to his local alliances; in the area of Gondor, Rohan, Aglarond, and Ithilien are all ruled and/or settled by personal friends; further north Greenwood, Dale and Erebor are unlikely to cause trouble; and in the area of Arnor, Celeborn still holds Imladris and the Dunedain are at Aragorn's command, with their fortress of the Angle.

The questions I would like to ask would be, for instance, how soon would it take for Arnor and Gondor to split into two kingdoms again? It's clearly impracticable to rule both, especially as the population increases. Once Elessar's line is split, so the loyalties of Elessar's historic allies would split, and North/South conflict might be possible.

If Florence is truly the site of Minas Tirith, then Gondor must have been wracked by civil war indeed to become anything like fractious Italy...

Also, would the Principality of Ithilien eventually become independent in practice? Likewise the Principality of Dol Amroth. Would a future ruler of Gondor endeavour to assert claims over Rohan? Would Rohan be content to remain a vassal? Etc etc.

As for the Haradrim, they can't be anything like wiped out. Harad isn't really a realm, it's anything South and unknown. But they're probably occupied with their own affairs after so heavy a defeat, at will be Easterlings and Khandings, for the moment...enabling Elessar to take the offensive. Will he make the same mistakes as earlier Gondorian rulers of the South did? I do hope so!
