I will paste the poem I've written so that you can get an idea of the context I've used them in. I will highlight the words with an asterisk on either side. Both are in the third
Suspense in the air, but hold not your breath,
the harsh nights are void, of the sandman's caress,
the innocent shan't fear, an *illusious* ideal,
but time's drawing near, for the *tortured's* last meal.
Hi Dr. Wu,
Although you can see I am not a native, I don't see why the word illusory wouldn't fit in here. Maybe there's an aspect of its meaning which escapes my understanding of it, but I think it conveys the image you need and it also fits in terms of rhythm.
As for "tortured's" in this context, in my opinion, it sounds OK: the last meal of the tortured man. I understand that you needed the Saxon genitive here for rhythm purposes only, and that the possessor (man) has been omitted for that same reason.
Hope it helps (and that it makes sense).
