That's right. :)

1. A proper plural and archaic form gives the black its English name.
2. Named for their master in the blackened green.
3. Known by where and what it is, home of gold.
4. Belted and counted; look three from the back.
IRON HILLS - Fear halved, an elementary rise for the new king.
NARGOTHROND - Elvish fire, depart! The hammer begins to be cast by the river.
GUNDABAD - Firearms - the evil in the north.

Elvenking's Halls?

That sounds like a possible underground realm. Can you fit it to any of the clues?

hS

Is 3 EREBOR?

Known for being the Lonely Mountain.

For 2.

Is 1 DWARROWDELF? Tolkien's preferred plural for dwarf (in English) was the archaic dwarrows/dwerrows (which I think he wrote ought to have existed, or something), and Moria was the black chasm.

Could password be DEEPING?

No, but also yes, so I'll give you that.

In that case yes. :)

Exactly that.

It could be... if this were a different puzzle.

DWARROWDELF - A proper plural and archaic form gives the black its English name.

LONELY MOUNTAIN - Known by where and what it is, home of gold.

IRON HILLS - Fear halved, an elementary rise for the new king.

One to go!

Delving!

Correct!

This is the one clue I couldn't find a word with the right initial for.

hS

Is the 'blackened green' of clue 2 Mirkwood?

Yep; Greenwood becomes Murky.

hS

Them elves and their decadent ways. Drinking at all hours.

I guess there are two letters after V.

There are indeed.

hS

Is it ------------ Caves?

Glittering Caves, perhaps, but how are they belted and counted?

Caves, but not the Glittering ones. One half of 'belted and counted' is a straight clue.

hS

4. Caves of the Forgotten?

Not that either.

One of 'belted' and 'counted' is a clue to the realm as a, um, realm; the other is a direct clue to the name.

hS

Then I will leave it to others.

Btw, a bit of self promotion, but no guesses for my riddle? It's easy......

I guess it must be the Thousand Caves? Regarding 'belted' ... they are also called Menegroth. Is 'Mene' belt, since I think 'Menelwhatsisface' is Orion, the constellation with the shining belt?

...

No Angband or Utumno, then? ;)

It is the Thousand Caves, which are famously within the Girdle of Melian.

DWARROWDELF - A proper plural and archaic form gives the black its English name.
ELVENKING'S HALLS - Named for their master in the blackened green.
LONELY MOUNTAIN - Known by where and what it is, home of gold.
THOUSAND CAVES - Belted and counted; look three from the back.
IRON HILLS - Fear halved, an elementary rise for the new king.
NARGOTHROND - Elvish fire, depart! The hammer begins to be cast by the river.
GUNDABAD - Firearms - the evil in the north.

Mene in this case is meneg, 'thousand'; in the constellation, I think it's menel, 'heaven'.

Over to you, Pervinca.

hS

True ... I then remembered 'O menel aglar elenath' and realised that I was talking pants. :D

Another interesting password, so this one might disappoint. However, if the theme is still unguessed at the end *and* I can work out the answer to Huinesoron's 'One Thing In Common' question, (highly unlikely!), I might drop the answers in there as well. As far as I am aware, and with one caveat that I will explain, I think these are the only examples pertaining to this theme.

Here we go, then:

1. French valley lingerie? No way! Mix it up for him.
2. A handle and the French one are in turmoil for her.
3. After an awful, unsung muddle, forty-nine with reveal her.
4. She sounds like a silly one, the Spanish girl.
5. Spouse around a way for him.

By the way, in my clues, from now on, sing/sang/sung can mean a note, and unsung/unsing can mean take a note away.

4. Niniel (Nina+El)

1. French valley lingerie? No way! Mix it up for him.
2. A handle and the French one are in turmoil for her.
3. After an awful, unsung muddle, forty-nine with reveal her.
NINIEL: She sounds like a silly one, the Spanish girl.
5. Spouse around a way for him.

It IS Niniel, but it's NINNY + EL.

2. Earwen (Ear+un)

Nope.

I'd be pretty annoyed if someone used my ears as handles!

Well, ear is a synonym for handle.

1. French valley lingerie? No way! Mix it up for him.
2. A handle and the French one are in turmoil for her.
3. After an awful, unsung muddle, forty-nine with reveal her.
NINIEL: She sounds like a silly one, the Spanish girl.
5. Spouse around a way for him.

Apologies. I made a mistake in clue 5. Now amended, in every post it appears in.

5. Finwe (Wife around N)

Password is Turin. Yeah, I deducted that from only two answers.

You didn't.

You may, however, have *deduced* it. :D

1. French valley lingerie? No way! Mix it up for him.
2. A handle and the French one are in turmoil for her.
3. After an awful, unsung muddle, forty-nine with reveal her.
NINIEL: She sounds like a silly one, the Spanish girl.
FINWE: Spouse around a way for him.

Hurin, then?

???T???: French valley lingerie? No way! Mix it up for him.
???U???: A handle and the French one are in turmoil for her.
???R???: After an awful, unsung muddle, forty-nine will reveal her.
NINIEL: She sounds like a silly one, the Spanish girl.
FINWE: Spouse around a way for him.

It's Turin. I just forgot to put the password letters in.

Whoops! A typo in the R clue. Now fixed.

3. Miriel?

2. Urwen (UN+WER)

WER is an abbreviation for handling services, in case you didn't know.

No and no.

Well, if the theme is husband and wife, then Miriel must be an answer to 3.....

If it was the answer, I would have said so.

Then the theme is not husband and wife?


I am confused here. There are only two relationships between Turin and Niniel: husband and wife, or brother and sister. But Finwe has no sister, thus it must be husband and wife. And only one of Finwe's wives contains R, and it's Miriel.
