The inscription of the name of Thor on this runestone has partially faded away. Solve this sudoku to help restore it.

RULES:
- Standard sudoku rules apply.
- The numbers outside the grid indicate the sum of the digits in the direction of the arrow.
- There are 5 palindromes in the grid, indicated by the remaining red lines along each rune (ᚦ, ᚢ, and ᚱ) and the red lines above and below the runes. The digits along a palindrome have to form the same sequence independent of from which end you start.
(To be absolutely clear, the palindromes have the following endpoints: R5C1 -> R1C5, R5C1 -> R6C4, R9C5 -> R5C9, R1C7 -> R5C9, R4C6 -> R7C7)
