One pole, fixed forever (the bright star). Two continents drift beneath it. Each continent's rocks record only where the pole sits relative to itself — so each builds its own "apparent polar wander" path, and the two paths disagree.
The disagreement is the proof: the pole never moved. The continents did. This is how paleomagnetism showed the ground we stand on is adrift.
DRAG either continent to move it. Each leaves a recorded wander path in its own frame. Press REASSEMBLE to lock them back together — the two records snap into one.
