This is the sequel to Toroidal Treasure Map. Thanks to all my testers for their time and feedback.

These puzzles are intended to be solved by a pair of solvers, with each solver seeing only one of the puzzles. Solvers are encouraged to communicate any and all information verbally, and use of the coloring and line tools is likewise encouraged. Coordination between solvers using these tools is indispensable.

Rules:

Normal Sudoku rules apply.

Cross-Grid Toroidal Borders: Line and cage clues which exit one grid will enter on the opposite side of the *other* grid in the same row or column. For example: a clue which exits one grid at r1c5 (at the top) will enter the other grid at r9c5 (at the bottom).

Normal killer cage rules apply. Digits may not repeat in a cage, and sum to the total (if given). All cages marked with a ? must contain different digits (across both grids).

Landmark Clones: A landmark is a group of the same symbols or a line. Each landmark contains the same digits in the same relative positions in both grids. Rotations and reflections are not allowed. Landmarks include Mountains (triangles), Forests (arrows), Caves (diamonds), Lakes (hexagons), and Rivers (lines). Rivers may cross grid borders (other landmarks may not).

Playable Example:
The following images show a completed playable example. Both 6x6 grids are shown at the same time in the example.
