Full grid, author translator, world, shading indicator all in order and final letter ringed to complete the thematic set. I’m struggling a bit with interpreting the shading indicator though. I have a notion that it means 6, 7, 1 in contiguous cells. If that’s right it would resolve the unches in 12a.
Certainly a challenge! Some very chewy clues with the additional layer of jumbling to manage. A lot of rubbing out and reordering for me! But thank you to Raven for keeping me engaged for several hours of quite strenuous mental exercise.
