Quick crossword No 391

Hi emaherself and thanks for a great little crossword! Plenty to fuel the imagination and satisfy the intellect, with some standout surfaces. My picks of the bunch were 1a, 11a, 15a, 3d, 5d, 6d and 20d for sheer bonkersness! Minor afterthoughts…

I thought it was brilliant. As someone relatively new it was perfect level for me. A genuine challenge and lots of very satisfying clever clues. Thank you.
