Royal Marriage

King Elessar weds Arwen Undómiel upon Midsummer 1419, thirty-nine years to the day after they plighted troth under the trees of Lórien. Sixty-eight years have passed since they met in the woods of Imladris, eighty-eight since Aragorn was born to Arathorn and Gilraen, and 2,778 years since Arwen was born to Celebrían and Elrond Half-elven.

Aragorn Elessar is the Heir of Isildur through thirty-nine generations, Chieftain of the Dúnedain of the North and, after the War of the Ring, King of the Reunited Kingdom of Arnor and Gondor. Called by Gandalf 'the greatest traveller and huntsman in this age of the world', Aragorn experienced many great adventures, and travelled to many distant lands, before claiming his kingship.

Arwen Evenstar is the daughter and youngest child of Elrond and Celebrían, born in the third century of the Third Age. She lived out her long life at her father's House at Rivendell, and also at times among her mother's people in Lórien. In the year III 2951, when she was 2,710 years old, she returned from a time in Lórien to meet the young Aragorn, at that time being fostered by Elrond.

LOTR:  The Fellowship was forced down from the mountain pass and into the mines when Saruman conjured a terrible storm from atop the tower at Isengard. Saruman was protected by the great circle around Orthanc, a shield the Ents easily compromised. They could not make a dent in the tower of black rock, but  restored the beautiful garden after the wizard fell.

The wealth of Moria was not in gold or jewels, but mithril...    
Durin discovered the caves above Azanulbizar, linked to a lane near Lothlórien, home of Galadriel and Celeborn. Dwarves carved mines within the Misty Mountains that were "vast and intricate beyond the imagination,"  in the search for mithril until T.A. 1980.

They released an ancient Balrog in the deep mines of Khazad-dum and the realm was abandoned, thereafter known as Moria, the black pit.  Other names for mithril are Moria silver and true silver. Bilbo gave Frodo a shirt of mithril worth a king's ransom - mail "light as a feather and hard as dragon scales."
