This is the fourth in my "Power of the Knights" series.

The entire series can be found here

Rules:

Normal Sudoku Rules Apply

Any two cells separated by a knight's move (in chess) cannot contain the same digit.

Cells connected by X sum to 10. Cells connected by V sum to 5. Not all Xs and Vs are given.

Cells connected by white dots are consecutive. Not all white dots are given.

The gray lines are palindrome lines, and must read the same forwards and backwards.

Additionally, the 5 palindromes represent "Knights". Each knight has a rank equal to the length of the palindrome line which represents it. The sum of all values on a palindrome line is equal to the rank of the knight to the second power. i.e., the digits on a palindrome of length 3 will sum to 3^2, or 9.
