This puzzle was made as an attempt to immitate Andrewsarchus. The two main puzzles I used for inspiration were Triad and Trisection. I hope you enjoy!

Rules
Normal sudoku rules apply.

Disjoint Groups: Cells in the same relative position within their boxes must not contain the same digit.

Modular Lines (teal): Any set of 3 sequential cells on the line must contain exactly one digit from {1,4,7}, exactly one digit from {2,5,8}, and exactly one digit from {3,6,9}.

Region Sum Lines (blue): Box borders divide blue lines into segments. Segments on the same line have the same sum. Segments on different lines may have different sums.

'V's separate digits which sum to 5.
'X's separate digits which sum to 10.
