This is the prelude to the Lord of the Rings Trivia though posted posthumously by J.R.R Tolkien's son christopher Tolkien. This a must read for the people who wishes to know more about the environment and history of the LOTR in which it is set. The story starts of with Iluvatar the supreme god creating the world of Ea from a symphony and void. The Ainurs (Components of the symphony who are the gods of the world) or Valar descend into Ea to chisel out the world to perfection. As usual we have Melkor the evil Ainur planning with his devisive ways to corrupt the first children of Iluvatar - Elves. What ensues further is the war of the Ainurs with Morgoth alias melkor and chaining him up in the tomb of Mandos in the First age.
The Elves themselves are of three clans headed by Ingwe of vanyar, Finwe of Nolder and Elwe and Olwe of Sindar.Thus we enter into the second age with the elves living in Valinor, the blessed realm of valars. But Melkor gets released and by this time we have Feanor a master craftsman, son of Finwe, creating the three silmarils, the jewel blessed with the light of Trees created by Yavanna (Valar) which is abducted by Morgoth.From here on the story concentrates wholly on the line of Finwe's sons(Feanor,Fingolfin,Finarfin) and to some extent on the line of Elwe (Thingol). Most of the anecdotes in LOTR are described in detail, eg-Beren and Luthien's affair, Ring of Barahir(given to Barahir by Finrod Felagund), Castle of Thangorodrim.
After many deaths in Nolder's line in the hands of Morgoth's host, Earendil the half elven sets on a voyage to seek the help of valar themselves. The valar ambushes Morgoth's Followers and the infamous Lieutinent of Morgoth,ie.Sauron who sheds off all evil after the battle fearing the Valar.Morgoth is pushed into the void for all ages permanently never to come back.Most of the Nolder return back to Valinor, but some of them remained back. eg gil-galad son of Fingon, Celebrimbor Grandson of Feanor & maker of the Ring, Galadriel daughter of Finarfin, Cirdan the Shipwright who even in LOTR takes Elves to Valinor and Elrond - son of Earendil. The infamous Battle of Fingolfin with Morgoth and Fingon with Gothmog are depicted greatly.
The Sons of Earendil are Elrond and Elros. Elrond chose to be an elf while Elros represented men. He was known as the Tar-minyatur from whom the race of the Numenor starts.After 2000 years The heart of the numenoreans is blackened for the need of immortality and Sauron uses this as his high time to put an end to Numenorean race.The Might of the Numenoreans could be figured out when sauron surrended to Ar-Pharazon, king of numenor though sauron wielded the ring at that time. Though Sauron's cunning devices kills Numenoreans, Elendil and his sons Isildur and Anarion survive and comes to Middle-Earth to start the age of men in Middle-Earth.The rest could all be found in LOTR. Many questions of ambiguity in LOTR (like where & why Elves are going to the west in ships) would have it answered in THE SILMARILLION.
Ouch! i forgot to tell the destiny of the silmarils. one of the silmarils would be recovered from Morgoth's crown by beren and luthien and put up in the sky, but the other two would be put up in fire and Water of Ea.
