This was quite the challenge from Prak, and a pangram.
A very fun solve, which took me a couple of sittings to complete, with at least one use of a word-search, and numerous bits of research to solve/confirm answers.
That is absolutely not a complaint, as I genuinely enjoy those little diversions into learning about Anglo-Polish writers, old fashioned instruments or stage performances, and a type of dragon I only knew from a place name.
My last one in was SEQUESTERED, where the likely Q to complete the pangram helped a lot.
I did notice the puzzle has fewer clues than most 15×15 grids at 26 (I count them to track my progress when solving for personal moral support, as I do with kilometres when running long distances) but I don’t think the puzzle is any the worse for it.
Many thanks to Prak.
