The collision has cancelled any remaining movements, the turn ends and all remaining movement is lost when the collision starts.Rulebook page 13:
When the Nautilion’s movement would cause it to move past the Phantom (or vice versa), the moving figure ends its movement directly in front of the non-moving figure (but after the token instead of on it, as usual), and the turn ends immediately: all remaining movement is lost and the collision begins.
