[Nerwen]

1. Incarnation has a solitary element in this land of shadows.
2. Unsettled surfeit for the insatiable.
3. As he reflected, he lived in high places, in the company of a noblewoman.
4. Legendary one walked valley, bewildered, in dreadful mountains.
5. A mighty avant garde soloist, in retrograde. Or is that an echo?
6. Twice-twisted suffering? We have come to a pretty pass.
7. A venomous insect, yes- but me, a mixed-up globule? Take it back!
PHIAL OF GALADRIEL: Star-power? She bottled it!

#2 is not the Silmarils but something closely connected to them. "The insatiable" is indeed Ungoliant, but "unsettled" and "surfeit" are on the cryptic side.
