King's Guard
Normal sudoku and killer rules apply. Eight of the digits are "Knight" digits. Two identical knight digits cannot be a knight's move apart. The remaining digit is the "King". Two king digits cannot be a king's move apart. Additionally, the king in box five must be a knight's move away from each of the knight digits.
Solution code: Rows 3 and 8

"Additionally, the king in box five must be a knight's move away from each of the knight digits." What a surprising effect this had. Wow

Very fun puzzle! The logic for figuring out the king was superb, and the rule about box 5 led to a really beautiful and unique logic.

We're the Knights of the Round Table, we dance whenever we're able!
Every part of this puzzle was fun - identifying Arthur, finding Camelot in box 5, figuring out the seating plan for the Knights of the Round Table. Enjoyed it a lot.
I got stuck several times, but then always realized what simple and natural logic I had overlooked. So I think that - as with many great puzzles - it's not so much about fighting hard for any small deduction, but more about looking at the right spot at the right moment.
Thanks!

This was actually pretty hard, I did not expect that from the outset. Great work!
