[The Might]

So much posting...
Anyway, zxcvbn (you really must change you name) I believe WCH is correct about the WK only having been reduced to impotence till the destruction of the Ring and him dying afterwards.
I thought he was around myself, forgot however that the note was reffering to the time before the destruction of the Ring.

Gwathagor...

"Thus spake Mandos in prophecy, when the Gods sat in judgement in Valinor, and the rumour of his words was whispered among the Elves of the West. When the world is old and the powers grow weary, then Morgoth, seeing that the guard sleepeth, shall come back through the Door of Night out of the Timeless Void; and he shall destroy the sun and the Moon. But Earendel shall descend upon him as a white and searching flame and drive him from the airs. Then shall the Last Battle be gathered on the fields of Valinor. In that day Tulkas shall strive with Morgoth, and on his right hand shall be Fionwe, and on his left Turin Turambar, son of Hurin, coming from the halls of Mandos; and the black sword of Turin shall deal unto Morgoth his death and final end; and so shall the children of Hurin and all Men be avenged. ~ BoLT II, VI

And a bit different:

"Thus spake the prophecy of Mandos, which he declared in Valmar at the judgement of the Gods, and the rumour of it was whispered among all the Elves of the West: when the world is old and the Powers grow weary, then Morgoth shall come back through the Door out of the Timeless Night; and he shall destroy the Sun and the Moon, but Earendel shall come upon him as a white flame and drive him from the airs. Then shall the last battle be gathered on the fields of Valinor. In that day Tulkas shall strive with Melko, and on his right shall stand Fionwe and on his left Turin Turambar, son of Hurin, Conqueror of Fate; and it shall be the black sword of Turin that deals unto Melko his death and final end; and so shall the children of Hurin and all Men be avenged." ~ TSoMe III, 19

"When the world is much older, and the Gods weary, Morgoth will come back through the Door, and the last battle of all will be fought. Fionwe will fight Morgoth on the plain of Valinor, and the spirit of Turin shall be beside him; it shall be Turin who with his black sword will slay Morgoth, and thus the children of Hurin shall be avenged." ~ TSoMe II, 19
