Thanks to Lulero for helping me find a valid grid. The rule set is based on earlier "Octopus Rules" puzzles by ThePedallingPianist. If you are bothered by the dark background, you can play a light version here.


Normal Sudoku rules apply.

OMNIPUS
- Draw 4 Region Sum lines, all with the same length, each having 180 degree rotational symmetry around the center of the grid.
- Every cell in the grid (besides the center cell) is visited by a line exactly once.
- Lines may cross other lines (but not themselves).
- Lines end in cells on the edge of the grid.

ORBS - A clue on a small white orb (which burns in your mind even with eyes shut) indicates how many times it is crossed by a line. The orbs, oh God, the orbs...

RUNES - Matching runes are on the same line. The same line! Hah! Hah! The same, always the same!!

REGION SUM - Box borders cut lines into segments with the same sum (how cruelly they cut!) which may be different for different lines! All is forsaken!!! Cthulhu fhtagn!!!
