Oh well....

ARWEN: Diminish, with direction, for a noble maiden.
N: The Nazgul are in disarray, alternatively, for her.
C: Note a wild goose for her.
A: Combine a note and an element with wrath for her.
L: Every language in turmoil for her.
I: Bloomers are in turmoil for her.
M: Initially, ride or move. Not old? Reverse and see her.
ERENDIS: Before direction and a dwarf woman, she appears.

7. MORWEN.

M O R (initials of 'ride or move,' reversed + NEW reversed).

N: NIENOR: nine + or

N - NIENOR (NINE in disarray, plus OR).

Well, it looks like mothers and daughters, but there are nine names. Maybe one is a trio and includes Grandma. :D

Whoops! Crossed with G55.

ARWEN: Diminish, with direction, for a noble maiden.
NIENOR: The Nazgul are in disarray, alternatively, for her.

Or it includes a mother and her two daughters.... ;)

(Having one trio was the only way I could reasonably make this password.)

I get LAL for ALL (every).

But AITH for language?

There's no U, so the other daughter can't use her birth name. ;)

C has to be CELEBRIAN, because we don't know the names of Arwen's daughters. But I wanted the goose to be EIDER.

Hang on ... is an eider a duck? :D

Or is it goose as in silly person?

There's brain in Celebrian ...but cele can't really sound like silly.

Yes, ALL+THAI

BERNICLE+A

ARWEN: Diminish, with direction, for a noble maiden.
NIENOR: The Nazgul are in disarray, alternatively, for her.

LALAITH: Every language in turmoil for her.
I: Bloomers are in turmoil for her.
MORWEN: Initially, ride or move. Not old? Reverse and see her.
ERENDIS: Before direction and a dwarf woman, she appears.

I think the final pair is ANAIRE (A + Na + IRE) and INDIS. But I don't know of a flower called an indi or a dini or a nidi!

(REALLY kicking myself over THAI!)

Anaire is correct, but Indis is not. Take another look at that family tree.

ARWEN: Diminish, with direction, for a noble maiden.

Hint: Two of my favorite characters are Anaire's grandkids, and another of my favorite characters is her daughter.

IRISSE.

Another name for Aredhel.

I figured it could only be Aredhel and she must have another name. Wondered if it was Ar-Feiniel and not a first letter answer. Then looked a bit further.

Iris ... oh - irisES! Clever.

I THOUGHT Anaire as another sister to Findis and Irime wasn't right! Must have missed the =. Eyesight ....

Another excellent password, Urwen!

Thank you.

It's yours.

Just checked how I did my mothers and daughters one. Four pairs, but I had to run one of the names backwards. I'll post it for you when my laptop is next online.

For now, I just have this one. As it's only 3 clues, I'll just copy it out on my phone. I do have one other all planned, but I haven't written the clues yet. So:

1. Naught splendid about him.
2. More exquisite direction is what he's all about.
3. It's a strain and a muddle to find her.

1. Maeglin, from GLEAMING

Good try, but no.

I am curious to see what this is. Based on number of letters, I thought the password to be EOL or DIS, the only three-letter names I know of.

You quoted a third only today: OIN!

Then there's ORI and NAR.

SAM, BAN, RAN ... even PIP, stretching it a bit.

And ERU.

And MAY.

I assume muddle is an anagram indicator?

2. Finwe (FINE+W)

Yes regarding muddle.

Fine is right ... but if you read the clue carefully, it's asking for the comparative adjective.

Finer?

Well, let's see.....

FINER+N
FINER+S
FINER+E
FINER+W
FINER+D
FINER+L
FINER+R

Maybe GLORFINDEL (He contains FINER, and also three directions: L, N and D)

2. FRIEND, from finer? Maybe that can stretch into Elf-friend somehow?

Edit: xed with the last couple guesses.

One of the above combinations is right.

Not Glorfindel, and no extra letters.

And not Friend.

One of the above, is what I meant.

1. ANGROD is almost no grand. But there's a letter gone missing, and that's not indicated by the clue.

ANGROD: Naught splendid about him.
2. More exquisite direction is what he's all about.
3. It's a strain and a muddle to find her.

It absolutely makes Angrod.

It's 0 + GRAND.

Ohh, naught is zero!

Frerin (FINER+R) for 1?

ANGROD: Naught splendid about him.
I: More exquisite direction is what he's all about.
SIt's a strain and a muddle to find her.

To be fair, Urwen did guess DIS or EOL.

And DIS as the password?

Wait, where did G55 guess DIS?

ANGROD: Naught splendid about him.
FRERIN: More exquisite direction is what he's all about.
S: It's a strain and a muddle to find her.

Clue 2, not 1. ;)

Yes. :)

3. ARTANIS (STRAIN+A, muddled)

She didn't. You did, silly! Read my post.
