Here are the entries in ASCWC 263 ("ENDING"), with my thoughts. Who is the winner? This is not revealed until the end.
Demon escapes imminent termination (6)
IMPENDING minus IMP; def. is "termination"
Very nice. Smooth surface, fair wordplay and definition.
Close friend in gaol's constrained (6)
Hidden word; def. is "close"
Do the British still write "gaol"? This clue was easy, but the surface works nicely.
What Gog and Magog do re Armageddon? (6)
Gog and Magog appear doing the "ending" in some Armageddon stories, and they both "end in g."
This one requires some outside knowledge, but also some lateral thinking. Nice.
Never say never, presumably! (6)
I'm unpersuaded. "Never" (not even once) doesn't match up with "ending" (it happened, then it stopped).
Shutting down sleazy gin den (6)
Anagram ("sleazy") of GIN DEN; def. is "shutting down."
Nothing wrong here. Why anyone would shut down a sleazy gin den, well, that's another question. A nice clue.
And the winner is...Luciano, for the escaping demon. I invite him to moderate the next one.
Thanks to those who played. I still think this group can survive. But I've been wrong before...
