Well, I've seen all the available characters and the closest I could come up with are Forlong and Fredegar Bolger.

T: Here, a biblical fellow returns, to meet an archaic palindrome and a sibilant ocean.
H: Half German article and liquid marketing. For him.
E: Place of mirth ... but it's not unmixed.

R: Brag - dubiously, at first, you hear - before chaos ensues to expose him.
EAGLES: Seasoned sailors have more than one of these. But be that as it may, it's mangled to reveal these majestic creatures!
TEARS: Not all of these are evil.
UMBAR: Does one hesitate to suggest a pub here?
ROSE: She's inflamed - and troubled.
N: One must dress, groom, prepare? - put nails in order, certainly - for them.

OSGILIATH: Is David's foe around here?
FORLONG: Beat a Weasley? He's there - but discombobulated.

T: Group of sheaves slightly disturbed by - or rather for - the first ones to kill.
HAVENS: They're beardless and bewildered.
ELANOR: A role reversed; an article swallowed; a girl revealed.

KNIGHTS: Merry and Pippin, in white satin? (For thus it sounds, in song).
I: A painter's choice - Rembrandt's, initially - and Goya's, finally - mingles to reveal him.
N: See this fearsome thing return, endlessly crazy, to endlessly deceive.
G: Aged apparatus collapses to reveal him.

Usually it will be one of the shortest of the available options, (in this case, Weasleys), won't it? Because they're generally easier to mix with other elements to form anagrams.

FLOG + RON = FORLONG.

First E: just find a synonym of cheer, and anagrammise it to get a place.

Joy, gladness, glee

Or maybe ERECH (from cheer itself)

T: Here, a biblical fellow returns, to meet an archaic palindrome and a sibilant ocean.
H: Half German article and liquid marketing. For him.

Can't believe I did that! ;) I meant to type 'synonym of mirth.' ;)

Now. Look up a word for a group of sheaves.

CLUESES, PRECIOUS (because I'm feeling Christmassy and generous):-

1. Two and a third of the remaining clues are from 'The Grey Havens' (because there's one that applies to this chapter but also to two others).

2. One comes from the same chapter as ERECH.

3. One is from 'The Scouring Of The Shire.'

4. One is from one of the 'Mordor' chapters.

5. One is from a Gondor chapter.

6. And one appears in quite a few places.

Old+Gear.....

Yes to OLD; no to gear.

Gildor? (OLD+RIG)

Bingo!

...

Yes indeed! He appears once more in the final ride to the Grey Havens.

First T is Tol Eressea (LOT backwards + ERE + S + SEA)

And for the remaining R, is Radbug (BRAG + D + U)

Spot on!
 

TOL ERESSEA: Here, a biblical fellow returns, to meet an archaic palindrome and a sibilant ocean.

GILDOR: Aged apparatus collapses to reveal him.

Indeed, because Frodo sees Tol Eressea from the ship and we are told of white shores and a far green country.

Four to go! :)

I might be Imrahil.....

Nope.

What's your reasoning?

Maria is Rembrandt's painting, and Imrahil has almost all letters of that.

Look carefully at what the clue is asking you to take from Rembrandt and Goya.

And what sorts of things does an artist have to choose?

Oh. Iorlas then.

OILS + R + A.

More clues?

The second N should be pretty straightforward.

So EI from LIE and AM from MAD


NEIAM?

Wrong synonyms.

Think what the fearsome thing might be.

Grond?

How can it be Grond when it begins with N?

Nazgul?

Yes!

Before I put it in, though, can you work out the cryptic elements?

Well, NAZ comes from ZANY

GUL comes from GULL.

Exactly.

The H clue is cryptic, but straightforward. Four elements in a row. No mixing up.

Liquid marketing? What is liquid marketing?

Well, there is Halbarad (HAL(F) + BAR + AD)

I don't think BAR is a german article, though.....

TOL ERESSEA: Here, a biblical fellow returns, to meet an archaic palindrome and a sibilant ocean.
HALBARAD: Half German article and liquid marketing. For him.
ERECH: Place of mirth ... but it's not unmixed.

GILDOR: Aged apparatus collapses to reveal him.

It isn't the article that's German. It's the word HALF. :D

So: HALB + A + R + AD(VERTISEMENT).

P and B are PLOSIVES
D and T are DENTAL PLOSIVES
F and V (and various other sounds) are FRICATIVES

... but L and R are LIQUIDS.

The remaining clue is my favourite. The 'them' is something there are three specifically reported sets of in ROTK, but no reported sets of in FOTR or TTT.

You forgot to put Nazgul in.

Well, there are three Elven Rings revealed in ROTK, that weren't revealed/mentioned in the other two books, but only two of those begin with N.....

NAZGUL: See this fearsome thing return, endlessly crazy, to endlessly deceive.
GILDOR: Aged apparatus collapses to reveal him.

Nothing to do with rings.

Or is it? ;) In Middle-earth, I mean. It is here (or should I say 'now?')

I don't understand.....


Unless you mean NOWHERE (NOW+HERE)

No.

There is something that happens 3 times in ROTK, and two words of the clue provide an anagram of it.

put nails in order?
