Just to get it out of my system as I have a brain-brake stopping me get beyond this but I have the feeling that 12 might be one of the Sons of Elrond even though neither seem to work in the slightest ( in the clue sense, I am sure they were gainfully employed as Middle Earth glamourous alternative to the Krays...).

To get it on the same page:

5. RINGWRAITHS, referring to the Witch-king? I think he rode in through the Great Gate after Grond smashed through it.

4. Grey Havens? Was Mithlond the only port to Valinor? I know Legolas built his own ship, but did he have to sail to Mithlond first?

It is, actually. Do you want to try and figure out which one, or shall I put him in?

Correct, though in the singular.

Not the Grey Havens; I think I said that Anfalas was what was meant by 'the long shore'.

THEODEN - The king stands before a warren, to devour him subjectively.
HIRLUIN - "Here, Lou - in!" Only fair, no?
EOWYN - No Gollum, but say "Oh! Win!" to claim sword and shield.
4. G? - Legolas' end by Gimli denoted on the long shore.
RINGWRAITH - 1, lord of what?
EOMER - The top and tail of a farmer's song, the head of a sea-maid - a king?
ARAGORN - One cloth trumpet for a walker.
THARKUN - Reported by the dwarves: lisping shark, one (French).
GALADRIEL - Listen, the crowned one is glad: add hay to reel.
AROD - A stick or a steed?
TOOK - He is taken past the family.
12. E? - Adam fell? Add one at the end, subtract six from the start, flip it around for one of two.

hS

4. GOLASGIL, Lord of Anfalas.

(LE)GOLAS + GIMLI - MI.

That's the one!

And on reflection, I'll give Mith ELLADAN for #12, but will withold the explanation in case anyone wants to guess. So that's complete!

Theme: Characters specifically mentioned in the narrative as passing through the Great Gate of Minas Tirith

Mostly right where you'd expect. Galadriel and Elladan arrive as part of Arwen's party; I believe Legolas rides Arod out during the same sequence, though it might be during the final departure. Theoden is dead by the time he goes through, but it still counts.

And with that, over to Pervinca again, I believe.

hS

Please, I need to know how the ELLADAN clue works, or it will drive me crackers.

ADAMFELL has to lose M and F and gain an N. How does that happen? F isn't the sixth letter from the start.

Hee, all right:

Adam fell? Add one at the end, subtract six from the start, flip it around for one of two.

The comma-delimited instructions apply to the separate words. ADAM -> add one to the end, by iterating the final letter by one = ADAN. FELL -> subtract six from the start, by removing the sixth letter of the alphabet from the beginning = ELL. Flip it around = reverse the words, so rather than ADAN ELL, we get ELL ADAN.

I know it's not spectacular. I was kind of on a numbers kick with the Ringwraith clue, and deeply annoyed that I couldn't just give that one as '1.', because I couldn't just make it 'Witch-King'.

And now really over to you.

hS

I thought 'iterating' just meant 'repeating.'

I... think what I was thinking was that in a programming context, when you cycle through a loop once, you can say you've iterated the loop by one, and also that you've iterated the counter of how many times you've done it by one.

I dunno; it's late and I'm tired. :p

hS

Oh well that explains why driving myself mad with Roman numerals wasn’t going to work. Tricksy.

I'd totally forgotten about Old Macdonald, and was wandering in bewilderment through the lines of 'Bringing in the Sheaves' and (even better) The Wurzels' repertoire.

Anyway:

1. Mix grub with radishes, at first, and see him emerge.
2. The French aims, if confusing, reveal him.
3. The floor of my grandfather’s house, if initially lost, reveals him. (Sing it!)
4. Toilet edge with a nasal change. A slight flush at the beginning will reveal him.
5. Troubled Plantagenet, I recalled, at first, but a king-in-waiting? Hmmm ….
6. He’s defined by two appendages.
7. He swam around, although this is against his nature, (that is, swallowing seaweed initially).
8. He can take his drink.
9. Invoice him.
10. A thing unfairly sold, twice? Second lost; direction gained. See him.

9. Bill?

Correct!

I can almost get SAMWISE for 7. swam + s(eaweed). Perhaps the remaining "ie" is in "this is". And swimming is certainly against his nature.

Yes, IE swallows the initial S of seaweed.

#1 grub is FOOD, and if I mix it with the first of radishes, I find FRODO.

#5: I'm not sure Catherine of Aragon was a Plantagenet, but she was certainly troubled, and if we add the initial of 'recalled' to her we find the king-in-waiting ARAGORN.

FRODO: Mix grub with radishes, at first, and see him emerge.
LEGOLAS: The French aims, if confusing, reveal him.
???L???: The floor of my grandfather’s house, if initially lost, reveals him. (Sing it!)

For P: I'm contemplating 'pip' as in 'pipped to the post'; I think I've heard it used similarly to 'a steal' when discussing a purchase. PIPPIP minus the last letter of the second instance, plus a direction (N), gives PIPPIN.

The Plantagenet kings were all called Henry, Edward, or Richard, none of which anagrammise particularly helpful. I have a feeling I'm being too literal.

The Pippin clue refers to the unfair selling (by high street banks) of PPI with loans. (Maybe I should have added 'relatively recently' and 'in Britain' ... G55 and Urwen, has this happened over the pond too?)

So, PPIPPI, lose the second letter and add N (at the end) for the direction.

...

The PLANTAGENET clue refers to the meaning of the word 'PLANTAGENET.' Tricksily, it does not actually refer to one of the PLANTAGENET family. But the name was adopted due to its meaning.

Yeah, I should have got that. -_- (This morning I heard an ad on the radio: "The deadline for PPI claims may have passed, but for all other claims--" NOT INTERESTED BYE.)

... I remembered that it was something daft and banal, but had to check what. It purportedly comes from the name of the broom plant, which means BROOM + I.R. = BOROMIR.

(So the problem was that I wasn't being literal enough, heh.)

For the first L, I can't get anywhere until I shake the haunting strains of 'My grandfather's clock was too big for its shelf' out of my head. Perhaps someone else will have better luck. :)

The clock was too big for the shelf, so ...?

(Don't shake that song away!)

Oh, I see.

Floor - F = LOOR

LOOR + I + N = Olorin

Not correct, I'm afraid.

Maybe we need to remove both F and L. In which case, we get OOR.

So the clock itself is on the floor, initially lost indicates lock...

Oh! The floor is a LOCKBEARER. ^_^ That's a good one, I like that.

For the last one, I think the 'toilet edge' is a rim, which changes its nasal into rin. So I'm going to go with OLORIN, though how 'olo' and 'a slight flush' go together I have no idea. ('olo' looks like the head of a stag beetle or something seen from the front... :eek:)

hS

It's LOO + RIN, with slight scrambling, I think.

Indeed. The floor was a CLOCK-BEARER ... lose the initial letter and you get ... GIMLI the LOCKBEARER.

Huey, it's LOO! Flush the LOO slightly to get OLO, plus RIN, (RIM after a nasal change, just as you said). [Edit: Green* explained this while I was typing this post).

Urwen, why does my phone keep autocorrecting URWEN to GREEN? ;) (See ....*) Anyway, Olorin (which my phone just autocorrected to Like) was an answer, but to the other clue. And now ... over to you!

Here is another.
