Det finns också Beren, som dog i slutet av Wolfsjakt. Carcharoth, den största vargen som någonsin skulle leva, hade redan biten av Bers hand och blivit arg från Silmarils smärta som brann magen. Han jagades av Beren, Huan, hunden, och Doriaths elvar, och även om Carcharoth slogs, blev Huan och Beren dödsdödade.

Luthien pledade dock med Valaren för att återställa Beren, och de kom överens om att få honom tillbaka till livet tillfälligt, så länge han och hans fru inte involverade sig längre i världens angelägenheter. Och när Beren dog av gammal ålder, skulle han verkligen gå bortom världens kretsar för att ta emot Mänens gåva.

Gandalf

Som en Istar, och därför en Maia, är hans sanna natur en helig ande, och hans fysiska form är bara en inkarnation , en avatar .

Men efter sin kamp med Balrog of Moria, där han lyckades döda det, spenderade han all sin vital energi och hans fysiska kropp dog också.

Det sägs att Eru själv ingripit (förmodligen på ett exceptionellt sätt, eftersom detta inte verkar vara normen) och gav sin anda att "gå tillbaka" till sin kropp igen, för att han var den enda Istar som stod trogen mot sitt ursprungliga uppdrag.

Den nya reinkarnationen var inte exakt samma som tidigare: han var tidigare känd som Gandalf the Grey , men när han kom tillbaka till livet gjorde han i form av Gandalf the White : Hans sanna potential blev nu avslöjad.

The wizards, also called Istari, were originally spirits of the order of the Maiar, the followers of the Valar. These were sent by the Valar to help and assist the peoples of Middle-earth against Sauron as he gathered his forces during the Third Age.
[...]
Their spirits remained immortal, and they aged only very slowly. However, their bodies could be killed: Gandalf did indeed die from his duel with the Balrog of Moria, and only through the intervention of Eru himself was he restored to his body.

Gandalf used his last measure of strength to slay the Balrog, throwing him down the mountainside in ruin. Gandalf's spirit then left his body, having sacrificed himself to save the Fellowship.
[...]
But Gandalf's spirit did not depart Middle-earth forever at this time. As the only one of the five Istari to stay true to his errand, Olórin/Gandalf was sent back to mortal lands by Eru, and he became Gandalf once again. Yet, as he was now the sole emissary of the Valar to Middle-earth, he was granted the power to "reveal" more of his inner Maiar strength. This naked power that lay within him was seldom used during the remainder of his time in Middle-earth, as his mission was essentially the same: to support and succour those who opposed Sauron. Nevertheless, when Gandalf's wrath was kindled his "unveiled" strength was such that few of Sauron's servants could withstand him.

Glorfindel

Glorfindel var en Elf, så odödlig av naturen: vilket innebar att han var oskadlig för åldrande, men kunde fortfarande dödas av våldshandlingar eller med stor sorg.
Han kämpade med en Balrog under Gondolins fall, på bergen som omringade den dolda staden och lyckades döda den, men han förgås också när den döende Balrog tog honom ner i berget med den (detta låter bekant ...) .

Normalt när en Elf dog, gick hans ande till Halls of Mandos där den väntade på att bli omformad och stanna kvar aman.

Glorfindel fick den unika chansen att gå tillbaka till Middle-Earth efter sin reinkarnation.

Glorfindel’s spirit passed to the Halls of Mandos, where he waited with the spirits of the other Noldor who had died during their war against Morgoth. But because of Glorfindel’s noble actions in life, his reluctance at the Exile, and his furthering of the purposes of the Valar by saving Tuor and Idril, he was re-embodied after only a short time. He had redeemed himself, and was purged of any guilt. Not only did his sacrifice get him an early pardon, it earned him great powers, so that he was almost an equal to the Maiar.
Eventually, Manwë sent him across the sea to Middle-earth, possibly as early as Second Age 1200, but more likely in 1600 with the Blue Wizards. If the latter date, he arrived just after the One Ring had been forged, Barad-dûr built, and Celebrimbor dead or soon to be so. While the Blue Wizards were sent to the east, Glorfindel’s mission was to aid Gil-galad and Elrond in the struggle against Sauron. He played a prominent behind-the-scenes role in the war in Eriador and the other struggles of the Second Age and Third Age. His part, though great, was mostly overlooked by the histories, because his immense, angelic power was not usually displayed openly.

Durin

Durin jag kallade den dödlösa var först och främst de sju fäderna i dvärgarna. Dvärgarna trodde att han skulle reinkarnera för att leva sju liv, varje gång med namnet Durin.

Alla kungar som heter Durin som följde Durin I (från II till VII) liknade i stor utsträckning Deathless i både utseende och sätt, vilket gav upphov till denna tro.

The Longbeards believed that Durin would return to them seven times, and in each reincarnation he will again be named Durin and reign as King. He did have six descendants that were named Durin, all were kings of Durin's folk.

Jag är förvånad över att ingen har nämnt The Dead of the Dead

"The Dead are following," said Legolas. "I see shapes of Men and of horses, and pale banners like shreds of cloud, and spears like winter-thickets on a misty night. The Dead are following."

"Yes, the Dead ride behind. They have been summoned," said Elladan.
