The power and nature of the Girdle of Melian

[Inderjit Sanghera]

its not working anymore because beleriand sunk under the sea, which had the slight consequence of killing melian (it did didnt it?)

No, she left for Aman, to go into Lorien, and maybe serve Irmo again. Or cry. Or wait till Elwe is re-incarnated. Or write for The Wall Street Journal.

Tolkien fiddled around with Melian's actions after Elwe's death. In BoLT 2, she met and lived with Beren and Luthien, until passing to Aman, whilst in the more up-to-date verisons, of HoME 11, in which the Fall of Doriath is incomplete, there are several (sketchy) versions of it, but all culminate in her leaving for Aman.
