Of course, easy. If I knew you are going to appear, I would have picked something very hard. Okay, please continue :)

What name did the Sindarin use for the 'Everlasting Whiteneness'?

Fanuilos.

Not sure if that isn't Quenya...
No, I am looking for something else.

It is Sindarin– it's a title of Elbereth.

How about Amon Uilos, then?

Yes, this is what I had in mind. :D

Who wounded Glaurung at the Nirnaeth Arnoediad?

Azaghal, Dwarf Lord from Belegost.

Yep. Your turn.

heres a semi-riddle

Where does the wealth of the middle finally rest?

Wonder what middle means...

On the brow of Eärendil?

Actually I have no idea what you riddle is about. . .maybe you could re-phrase it or come with a hint.

sigh... its too easy for me to give you a hint...

What, you mean the Silmarils? One in the air, one in the water, one in the fire-depths of earth?

no keep guessing, your thinking to small. think BIG!

Well, maybe it is Númenor you are talking about, in which case it would be at the bottom of Belegaer.

your on the right track with that guess, but alas it is wrong!

Gil, I think also for the sake of clarity it will be good to at last explain what the "middle" in your first post is supposed to mean. I took it as "Middle-Earth", but if it was a typo, it will be probably better to correct it so that no one else is confused. If not, you should maybe tell us what it is supposed to mean, middle of what, or at least tell us that it's an intentionally cryptic word.

Perhaps in Aman... I know of that sceptre of Numenor in Aman

I suppose it could be the Ascar. Doriath was in the middle of Beleriand, and its treasure ended up on the bed of that river.
