You're right about K1, brendan and the region has two Ks.
Yes for the animal/'familiar' - then it's a word like frosty for 'frightening' (I think it's a loose synonym but just about works).

Have about half the solves for this, but I'm struggling to make any inroads in getting the grid. Am afraid my initial idea for 1a is incorrect. I currently have the first letter of 'Tchaikovsky, say...' as the fourth letter of 1a. Any pointers/hints would be greatly appreciated xx
The first letter of "Tchaikovsky ..." is the second letter of 1a which is a 5 letter word meaning "goes off" as food might and also a word for "acquisitions" although it's not the first synonym that might leaps to mind - think what the victor in war might 'acquire'
