Denali (from denial)?
If correct:
You and The Man first got high on battery innards (7)
LITHIUM (lit + hi + u + m)
This junk era has a directive. (7)
I think we need a clue.
Mandate? (man has junk, date is a very short era 
)
synonym for junk + synonym for era = directive
MESSAGE (I think)
+++++
Confused Old Etonian roaming without a cry (8)
I think we probably need a hint at this point to continue.
It’s been over a week with no guesses and no hints, despite request. I motion we leapfrog this puzzle and defer the posting of a new puzzle back to KO, who got the most recent previous correct answer.
Is there a second?
I agree. I think after a week a puzzle unsolved must be bypassed and the game thus progress.
Playing off MESSAGE:
Elf embraces eccentricity because of DNA sequence. (6)
Sorry everyone - I didn’t see the hint request (I think partly because Discourse doesn’t send me a notification unless someone specifically replies to one of my posts), I assumed everyone had forgotten about the game over the holidays.
GENOME (gnome with E in it).
+++++
Last letter to the Corinthians (5)
If anyone wants to still try and solve my previous effort, it may help you to know (if you weren’t aware) that “Old Etonian” is often abbreviated to “OE”. Another (unrelated) hint is “Native American”.
I got the original GERONIMO, but the new one escapes me.
Is it OMEGA?
Yup, 2 out of 2! Corinthia is part of Greece. Carry on.
Playing off OMEGA.
There’s a lot of anger in Georgia regarding the addition to the House.(6)
GARAGE (Ga + rage)
They envisioned a psychotic role for actress. (5, 5)
Probably need a hint here.
“envisioned a” anagram
That’s 11 letters
Sorry about that. Change the clue to:
They envisaged a psychotic role for actress. (5, 5)
