Mournië
The black ship of Nienna.
Mournië lies at Hanstovánen at Haerast.
When Men dies they goes to the Halls of Mandos where Nienna gathers them in her hall Fui, from there they are send aboard Mournië after their final judgment and they sail now south to the destination of which only Eru Ilúvatar knows. "Then when she is laden, of her own accord she spreads her sable sail and before a slow wind coasts down those shores. Then do all aboard as they come south cast looks of utter longing and regret to that low place amid the hills where Valinor may just be glimpsed upon the far off plain"
But it was not all Men, though the most, who went aboard Mournië, some were kept in Fui while others were
driven off behind the hill and seized by Melkor who took
them. But those who sailed with Mournië were coasted down along the shores to Arvalin ( Eruman
/ Avathar ) where they were set upon the shore to dwell in the dark until the final end and battle.
